Debugging: Changing ode equation during integration
Hello everyone,
I’m imprementing an adjustment to my chemical reactor design regarding physical limitation, due to the kinetics the value of one specie goes negative (comuptationally correct, but not physically) to account for the "no more fuel no more reaction" scenario i introduced a if:
ReactionRate(2*ovr) = ReactionK(2)*C(4)* 1e6 /CatalystDensity; % kmol/kgcat/h
if y(ovr) < 0
ReactionRate(2*ovr) = 0; % kmol/kgcat/h
end
dydt(i) = NetRateProduction(i)*(1-VoidFraction)*CatalystDensity*mw(i)/G;
in this way the dydt=0 and the value after reaching 0 (or a small negligible negative value) should stay constant, but after integration i still see a trend that goes way past 0
-0.0978571895684889
-0.0978554762967198
-0.0978537439506636
-0.0978519924638089
since the Ode for this specie depends only on the ReactionRate if dydt+0 it should stay constant, or is an error due to the fact that to evaluate if the rate should be 0 or not i use y? i tried with the last value of y using the persistent variable
persistent y_prev
.
if y_prev(ovr) < 0
ReactionRate(2*ovr) = 0; % kmol/kgcat/h
end
%after the system of ODE
y_prev(ovr) = y(ovr)
how this happens? i tested with de-bugging to see if the Ode=0 if the condition on y is satisfied and eas zero, so a constant behaviour, but in the results the diminishing trend is still present.

Histogram with normal distribution curve
Hello,
I have the data x and want to plot it in a histogram with the number of observations on the y-axis. I want to show also the normal distributon curve overlaying the histogram. I define V = 0:0.25:7 to the define the edges of the bins. I would like to create several histogram of different data sets with the same bin edges.
Using "hisfit" you cannot define a vector for the bin_edges only the number of bins.
Code
x = data1;
V = [0:0.25:7];
figure(1)
hisfit(x, 20, ‘normal’)
Using "histogram" you can define the edges but when I want to show the normal distribtuion curve I only manage to show it with the probability density.
Code
x = data1;
V = [0:0.25:7];
mu = mean(x);
sig = std(x);
x_normalized = linspace(min(V), max(V));
y_normalized = normpdf(x_normalized, mu, sig);
figure(1)
histogram(x, V, ‘Normalization’, ‘pdf’)
hold on;
plot(x_normalized, y_normalized, ‘r’, ‘LineWidth’, 2);
Is there a possibility to plot the data in a histogram with the normal distribtuion curve with a define bin_width and number of observations on the y-axis?

Microsoft senior leadership update: EVP, Chief People Officer and EVP, Office of Strategy and Transformation
Satya Nadella, Chairman and CEO, shared the below communication with Microsoft employees this morning.
As we’ve seen time and again throughout our 50-year history, times of great change for the world and for our industry require us to have a mindset that enables us to continually adapt and transform ourselves. There’s no question that we are at the forefront of another such moment, with the rapid changes across every industry and business function in this AI era.
This means we must have the right product portfolio, the right business models, attract and retain top talent, and optimize our processes to meet changing customer expectations and succeed in the marketplace.
With this context, I’ve asked Kathleen Hogan to transition to a new role focused on defining our overarching corporate strategy and structure and leading our continuous transformation as a company. Kathleen will assume a new role as EVP, Office of Strategy and Transformation, reporting to me.
It is hard to overstate the impact Kathleen has had on Microsoft as Chief People Officer. Over the past 10+ years, she has led our cultural transformation, as we embraced a growth mindset, positioning us to seize new opportunities with agility and attract and retain world-class talent. She is recognized externally as a consequential HR leader transforming culture and the world of work. Her more than 20-year tenure at Microsoft, including leading our global services business, paired with her prior experience as a McKinsey partner in Silicon Valley, and a development manager at Oracle, makes her uniquely suited to lead this work as we accelerate our pace of change across our people, processes, and portfolio. Kathleen will work across the SLT as we chart this next phase of our transformation, which requires both interpreting the outside and redefining the inside.
Kathleen and I have been discussing this transition and succession planning for some time, and we both agree this is the critical juncture to apply new focus and intention to this work.
With this transition, I’m very pleased to share that Amy Coleman will assume the role of EVP, Chief People Officer, leading our HR organization. She joins the senior leadership team reporting to me.
Amy has led HR for our corporate functions across the company for the past six years, following various HR roles partnering across engineering, sales, marketing, and business development spanning 25 years. In that time, she has been a trusted advisor to both Kathleen and to me as she orchestrated many cross-company workstreams as we evolved our culture, improved our employee engagement model, established our employee relations team, and drove enterprise crisis response for our people. Amy’s commitment to operational excellence and high performance will be key in driving our continued success, and I’m confident in the perspective, expertise, and thoughtful approach she’ll bring as we navigate the next phase of our journey.
Please join me in congratulating Kathleen and Amy on their new roles.
Satya

How to split a table into multiple tables based on value in a column?
Hello,
I am reading in an excel file that has 2 columns of data. One of them has a lot number and the other has row/col numbers.
I’ve made a table that holds this information, however, I would like to make multiple tables for every set of lot numbers.
I’ve attached an example excel sheet. In this example there are 2 different lot numbers, so I would need it to make 2 different tables for each lot number with each corresponding row, col number! I also need it to be able to adjust if there are more than 2 different lot numbers because the sheet is always updated.

Listener not responding to ui slider
I didn’t like how the normal callback implementation on the slider only updated once I stop dragging it, so I tried addlistener instead, but for some reason it just doesn’t respond at all. As a simple example, for the following code
sld = uicontrol(‘Style’,’slider’);
lst = addlistener(sld,’Value’,’PostSet’,@(src,evt)disp(‘value changed’));
Changing the value of the slider directly from the Command Window ( sld.Value=0.5; ) causes the callback function to run, but moving the slider or pressing the arrows on its ends does nothing.

Excel Data preprocessing from a scattered one into an organised table
I have excel data that is pretty big (10000×63) and unorganised. I have attached the sample data file here (sample.xlsx).
This data is converted from a pdf to excel so there are a lot of issues. I will highlight some of them here.
Some key things to note about data
There are strings and numbers and I would like to keep them both organised.
After every 200-250 rows, the table header labels keep repeating which I would like to remove
Whenever the table header repeats, the columns shift left or right (sometimes upto 5 or 6 columns)
There is one column "Code" which has both strings(1,2) and numbers(2).
There are some cells where there is no data or "——".
There are some texts on the top and bottom of the table (legends etc) which I would like to remove.
I would like the data to look like this one big simple list (it took me 4 hours to make this). I would like to automate it as I have many excel files of similar dimensions(10000×63).
Additionally I would like to know if there’s a better way to organise this data other than matlab?
Thank you well in advance for your help. I am still learning matlab so any help would mean a lot!I have excel data that is pretty big (10000×63) and unorganised. I have attached the sample data file here (sample.xlsx).

Microsoft Ability Summit 2025: Accessibility in the AI era
Today, we hosted the 15th annual Microsoft Ability Summit, with over 20,000 attendees from 164 countries coming together virtually to discuss the future of AI and accessibility. Microsoft has a long-standing commitment to investing in accessibility, grounded in our business model and going back over three decades from the earliest accessibility features in Windows 95 and continuing today with new hardware and software functionalities powered by AI. We are innovating faster than ever before and people with disabilities continue to lead the way.
Accessibility is a fundamental right for people with disabilities and makes technology easier for everyone. We see this reflected in how customers are using Microsoft technologies around the world. Copilot for Microsoft 365 is unlocking workplace productivity like never before, more than 10 million people use Edge each month to have the web Read Aloud, over 1 million people use Immersive Reader to make webpages easier to read and partners like Tobii Dynavox and Special Olympics are bringing AI to people with disabilities globally. And these are just some of the highlights of what we shared today!
Here’s a quick summary of the new accessibility products, features and programs announced at the 2025 Ability Summit.
What’s new in 2025?
We announced that the Xbox Adaptive Joystick is now available for purchase exclusively at Microsoft Store. With more than 429 million players with disabilities worldwide, we know each player has unique needs and preferences for how they choose to play. The Xbox Adaptive Joystick is a singular, wired controller primarily designed to meet the needs of players with limited mobility. Its versatility helps players seamlessly incorporate it into their existing gaming setups. Built with the Gaming and Disability community who inform the development of Xbox products from the beginning. The joystick joins our family of adaptive accessories including the mouse, pen, adaptive kit and Xbox Adaptive Controller. For more details visit Xbox Support.
And all our Microsoft hardware comes in packaging designed to be accessible and sustainable. No more plastic clamshells! To help others with accessible packaging, today at the Summit, the Packaging and Content Team at Microsoft published its Accessible Packaging Design Guide, which offers practical guidelines, best practices and strategies to create accessible packaging and foster a trusted customer experience.
At the Summit, Microsoft teams and partners also shared ways they are working to further advance accessibility through technology:
- Tobii Dynavox is integrating Microsoft Neural Voice, a capability of Azure AI Speech, into their assistive communication solutions. This AI-powered feature gives more personal options for individuals who use assistive communication devices using eye gaze. Neural Voices are available in over 50 languages within their apps TD Talk and TD Phone.
- Microsoft Teams will improve for those using Sign Language View. Later this year, Teams will be able to identify when someone is using sign language and feature them prominently as a speaker in the meeting. These video customizations are part of our ongoing product development to help deliver clear and accessible communication for everyone.
- Copilot is powering neurodiverse talent. Recently, an EY study found that Copilot helped 76% of neurodiverse employees perform better at work by enhancing communication, memory recall and focus. At the Summit, we shared how new simple features like Team Reflow and PowerPoint Designer are helping people do their work. See four early adopters of Copilot in New York share their stories.
- AI comes to Narrator. Rich image descriptions powered by AI will be coming to Narrator in Windows Insider Preview this spring and Azure AI Foundry announced new UI improvements to reduce cognitive load.
- Over 5 million learners around the world have participated in our Accessibility Skilling program and we’re grateful to our partners including Teach Access, Computacenter UK and the City of New York. The free, virtual training includes the latest on AI and is available for organizations to use in their learning management systems.
- Speech recognition improved up to 60%. The Speech Accessibility Project, led by the University of Illinois Urbana-Champaign, unlocked a breakthrough improving accuracy gains for non-standard speech, and the Azure platform team demonstrated how developers can leverage GitHub Copilot to write accessible code.
- Special Olympics shared how Copilot has been a game-changing training companion for their coaches and athletes with intellectual and development disabilities for the Special Olympics World Winter Games in Turin, Italy.
All this progress is possible because of the people who design technology with accessibility in mind. In this way, technology benefits everyone, creating a more productive and efficient workplace. It is beautiful to see that reflected in this profile of Dave Dame, Senior Director of Accessibility and Human Factors at Microsoft, where he shared how accessible technology helps him thrive as a leader.
Onward
For over 30 years, Microsoft has focused on accessibility in our products. Accessibility makes our tools and technologies easier for everyone and accelerates innovation for the world. From the introduction of Sticky Keys and speech recognition in Windows 95 to Seeing AI in 2016 and beyond, accessibility innovations have benefited people in ways we designed for and ways we could have never expected. Just think about how closed captions are now invaluable for everyone watching videos and calls.
AI has the potential to create significant advancements across every sector of our economy and society. We will continue to be grounded and responsible in our approach as we work to get the latest technology to the people who can benefit from it the most.
Whether this is your first or fifteenth Ability Summit, thank you for joining and we hope you picked up a new feature, skill or nugget that helps you, your community or your organization get the most out of technology. All content will be available to watch after the event.
Let’s move forward together.

Inconsistency reading .mov video files
I have some .mov video files that I need to process. I use the "read" function to read them after creating the video object
vid = VideoReader([pathname videoID]);
numFrames = vid.NumFrames;
for frame = 1:numFrames
temp_frame = read(vid,frame);
end
I just do some image processing to each of the frames (temp_frame) and save the results that I am interested in.
Everything works fine. However, if I run the same exact code in another computer, the intensity of each temp_frame is considerably different. For instance, if I run just that piece of code on computer1 (Windows 11 pro) the mean, max and min image intensity values are 0.9615, 1 and 0.7098 respectively, and in computer 2 (Windows 11 Home) the mean, max and min image intensity values are 0.9920, 1 and 0.7569.
Does anyone know the reason of this discrepancy and how can I solve it?
