Adding variables to a plugin interface
Hello,
I’m working on a BiQuad plugin in Matlab. In the code, I generate the coeffients and use these to build the filter. I’m trying to figure out how to display the coefficent variables in the plugin interface window. Would anyone know how to do that and add it to the grid layout? Thank you.Hello,

Kundur Two-Area System Simulink Model (.slx) for MATLAB R2025b and Adding Distributed Generators
I am looking for a Simulink (.slx) file of the Kundur two-area power system model that is compatible with MATLAB/Simulink R2025b.
Specifically, I would like to know:
Where can I find or download a reliable Simulink implementation of Kundur’s two-area system (preferably already validated)?
If an existing model is from an older MATLAB version, what steps are required to make it compatible with R2025b?
Additionally, I want to extend the model by integrating distributed generators (DGs) into the system.
What is the recommended approach to add distributed generation units (e.g., inverter-based DGs or small synchronous generators) into the Kundur two-area system in Simulink?
Which Simulink/Simscape Electrical blocks should be used for modeling DGs?
Are there best practices for:
Connecting DGs to existing buses
Control strategies (e.g., PQ control, droop control)
Maintaining system stability after integration
Any references, example models, or guidance would be greatly appreciated.I am looking for a Simulink (.slx) file of the Kundur two-area power system model that is compatible with MATLAB/Simulink R2025b.

Inconsistent pressure, enthalpy and entropy from thermodynamic properties sensor and pressure sensor compared with CoolProp
I’m looking at the reversible heat pump example found here:
https://www.mathworks.com/help/hydro/ug/ReversibleHeatPumpExample.html
I run the example as-is, and then look at results in Simscape results explorer, focusing on three values calculated within S1: pressure from the Saturation Properties Sensor and enthalpy and entropy from the Thermodynamic Properties Sensor. I then move those plots to a figure and highlight three values at a single time:
The simulink model results give P=0.845676 MPa, H=423.098kJ/kg and S=1.87762kJ/kgK
However, when I use CoolProp within matlab to calculate entropy at the pressure and enthalpy combination I get a different value than given by the saturation properties sensor:
py.CoolProp.CoolProp.PropsSI(‘S’, ‘P’, 0.845676e6, ‘H’, 423.098*1e3, ‘R410A’)/1000

How to approach iterative data reading?
I’m working with a dataset that has 3 different arrays I’m interested in plotting: time, accel, and gcamp. They are all of equal size.
I’m using the accel variable as a threshold detector, where I define an arbitrary threshold under which any data I ignore. Anything above that threshold I use the index of that data point to grab the equivalent data points from time and gcamp.
How can I store this data in one structure so that I can iterate through it and generate statistics/plots about only the thresholded data points?
Something like:
time = [rand(1, 5000)];
accel = [rand(1,5000)];
gcamp = [rand(1,5000)];
sd = std(accel);
threshold = sd;
dumb = [];
for i = 1:length(accel);
if accel(i) > threshold;
dumber = [time(i), gcamp(i)];
dumb = [dumb, dumber];

end Hello,
I have imported data into two tables T1 and T2 34243X4 and 1070X8. To Compare the two tables I have padded T2 with string ’empty’ in all columns to match rows of T1. I am comparing T2(:,2) with T1(:,1) and which ever matches I then automatically the that particular row element in 4th Col of T2 will match row element of 1st Col in T1 (This acts as Sanity Check).
All the info in both the table is in string format including numbers
when I tried to use ismember is not able to match.
Did String Compare is not working or not comaring correctly.
Please could someone guide me. I have attached my code/script and also screenshots of my data.
Thank you for your time

Why are my MATLAB preferences not included during compilation in R2022a and later?
I have code that relies on a proxy setting included in my MATLAB preferences. In R2021b and earlier releases, this would automatically be included in packaging when compiling this code with MATLAB Compiler or MATLAB Compiler SDK. However, in R2022a and later, this no longer seems to be the case.

Requirements toolbox : How to add custom attribute from new column import from Excel file.
Hi everybody,
I am using the Requirement toolbox (R2023b update 4), importing requirements from excel (.xlsx file).
I followed the Mathworks example to make a first import with custom import options (as custom attributes), then i used to update from the requirements GUI after modifying requirements in the excel file (Click on Import file, and click "Update" on Requirement Interchange tab).
My problem is I need to add a column inside my Excel file, and a new custom attribute corresponding inside the .slreq file.
I cannot find how to change the import options as the requirement file already exists without importing a hole new requirement set so I will loose every links and update changes traceability.
Could you help me to find a way to change those options si when I Update the requirement set, the new custom attribute is added from the new column without breaking all my links ?
Thank you so much in advance!
Hope this find you well.Hi everybody,

Open to Work: How to Get Ahead in the Age of AI
Today is the day. Open to Work: How to Get Ahead in the Age of AI is officially available!
At a time when technology dominates the headlines, the conversation I see most often on LinkedIn is deeply human: what does AI mean for my job and my career?
And that makes sense. Careers once felt more predictable. Titles defined what you did. Progress looked like a ladder. That model has been evolving for years, but AI is accelerating the shift.
The most important truth about this moment is that the outcome isn’t written yet. The new world of work is being assembled right now, task by task, policy by policy, business by business. It will reflect the choices of the people who show up to build it.
That’s why Aneesh Raman and I wrote this book.
Open to Work is a practical guide informed by what we see across the global labor market and insight into the tools millions of people use every day. It’s for every person asking what comes next for their job, their career, their company or their community.
With help from experts and everyday LinkedIn members, it shows you how to engage with AI before you have to, how to adapt by focusing on what you can control and how to become irreplaceable by leaning into what makes you uniquely you.
And those ideas don’t just apply to individuals, they guide how we as Microsoft and LinkedIn are building for this moment. At the intersection of how work gets done and how careers get built, our shared goal is to connect people to opportunity and turn the tools they use every day into a canvas for human and AI collaboration at scale. Done right, that’s how AI expands opportunity and helps people build confidence and momentum in their careers.
We’ve always believed technology should serve people. AI should help humans. Not the other way around. That doesn’t happen by accident. It happens when we all decide to make it true.
If you want to go deeper on Open to Work, listen to my conversation with Microsoft President and Vice Chair Brad Smith on his Tools and Weapons podcast.
Open to Work is available now at linkedin.com/opentowork.
Ryan Roslansky is the CEO of LinkedIn and Executive Vice President of Microsoft Office, where he leads engineering for products like Word, Excel, PowerPoint and Copilot. Through these roles, Ryan is shaping where work goes next to unleash greater economic opportunity for the global workforce.
