Producing Clutter IQ for arbitrary Waveform
I was looking at https://www.mathworks.com/help/radar/ug/simulating-radar-returns-from-moving-sea-surfaces.html and saw that the radarTransciever() object has a phased.LinearFMWaveform() object attributed to it. Upon looking at this i realize there are only a few types of waveforms available, and it seems NO custom IQ waveform that can be created into a object like phased.LinearFMWaveform() that i can use to define in the radarTransceiver() object and therefore execute the receive(scene).
Ultimately i need to generate IQ off sea surface, with an arbitrary waveform i have predefined/computed.
Is there a way to define a custom waveform that is compatible with what i am trying to do above? or is there another way to generate IQ clutter return with an arbitrary waveform?I was looking at https://www.mathworks.com/help/radar/ug/simulating-radar-returns-from-moving-sea-surfaces.html and saw that the radarTransciever() object has a phased.LinearFMWaveform() object attributed to it.

splitapply does not retain ME stack
When the function that splitapply throws an error, this line number of this error is not include in the output (matlab2024b)
Example:
T=table([1:3]’);
G=findgroups(T);
splitapply(@fun, T, G);
function out = fun(varargin)

Announcing Open to Work: How to Get Ahead in the Age of AI
The work we do, and the way we do it, is always changing. Each of us has a memory of how we once did a task regularly, the tools we used and how both the task and the tools have since changed so much they are nearly unrecognizable. Because we are living and working in the “now,” change feels both personal and fast, so it is always worth remembering that this has happened before, maybe not in just this way or with this speed.
And it is true. AI is rewriting work. How we do our jobs. How roles change. How careers are built. The skills we need. Some of that is exciting. Some of it can feel overwhelming. What we remember and have learned from previous times is that in moments like this, people are open to work and don’t just need new tools. They need a new mindset, a clearer understanding of what’s changing and a path forward.
That’s why today we’re announcing Open to Work: How to Get Ahead in the Age of AI, LinkedIn’s first book, by CEO Ryan Roslansky and Chief Economic Opportunity Officer Aneesh Raman. The book explores how AI is reshaping work and what that shift means for the people navigating it every day.
Microsoft and LinkedIn sit at the intersection of how work is done and how careers are built. We share a belief that the future of work will be driven by human creativity and ingenuity, not technology alone. When humans stay at the center, AI amplifies what people do best and creates new economic opportunity. Open to Work is grounded in that belief and focused on what’s happening now, not abstract predictions about the future.
Ryan’s leadership at LinkedIn and as head of engineering for Microsoft 365 Copilot gives him a rare perspective on this moment. He sees how AI is built, how it shows up in everyday work and what it takes to adapt. Aneesh’s role gives him unique insight into how together we can use this moment of change to create economic opportunity for every member of the global workforce.
The book is backed by real data — insights from experts, LinkedIn’s global network, Microsoft customers and the Work Trend Index. The goal isn’t hype. It’s clarity about how work is changing and how people can respond in practical, meaningful ways.
For professionals, Open to Work is about agency — what you delegate to AI, what skills to deepen and how you stay relevant as roles evolve. For leaders, it’s about rethinking how work gets organized and cultivating a Frontier mindset: the conviction that the most important innovations happen at the edges, where uncertainty is highest and the opportunity to shape what comes next is greatest. And for Microsoft and LinkedIn employees, it’s a reminder of the responsibility we share to shape the future of work in a thoughtful, human-centered way.
Open to Work publishes March 31 and is available for pre-order today.
Frank X. Shaw is responsible for defining and managing communications strategies worldwide, company-wide storytelling, product PR, media and analyst relations, executive communications, employee communications, global agency management and military affairs.

An easy way to input song chords into a structure of MATLAB
Hello. I’d like to know the way to enter the name of the song chords into the structure of MATLAB easily.
I do research about the related between chords and a piece of music, and I analyze the chords progression in MATLAB. Howerver, it takes too many time to enter the name of chords by hands like this;
chords = struct( …
‘name’, {}, … % name of chords（ex: ‘Cmaj7’）
‘start_sec’, {}, … % start time[s]
‘end_sec’, {} … % end time[s]
);
N=input(‘the number of chords: ‘);
BPM=input(‘BPM: ‘);
chords(1).start_sec=0;
for i=1:N
fprintf(‘n===== Chord %d =====n’, i);
chords(i).name=input(‘Name: ‘); %”
Start=input(‘Start beat: ‘);
chords(i).start_sec=(60/BPM)*4*(Start-1);
if i >= 2
chords(i-1).end_sec=(60/BPM)*4*(Start-1);
end
end
ends=input(‘End beat: ‘);
chords(N).end_sec=(60/BPM)*4*ends;
save("chords_yoruni.mat","chords");
I am a beginner when it comes to programming, so I don’t have any idea. I would like you to tell me even small things.

How to check that a matlab.ui.Figure handle is deleted?

Variables Window unusable in Matlab 2025
Unfortunately, the switch to MATLAB 2025 has made the Variable Editor unusable. This is due to two issues:
Variables are not displayed immediately in the Variable Editor. When double-clicking a variable in the workspace, sometimes one and sometimes two windows open—one of which is always empty and shows a loading circle.
When using copy-paste, entire rows or columns are no longer copied. Instead, only a portion is copied, which changes simply by scrolling within the Variable Editor.
As a result, I can no longer use MATLAB effectively, since I frequently need to copy and move large sets of measurement data.
Is this a known issue, or is my PC simply too old/slow/faulty?

How to share the same Referenced Configs on Multi-rate systems
I am working on a project with different Software Components in Simulink. The Components are intended to share the same Configuration. However the Sampling time can differ. For this purpose, the Sampling time is defined as a variable "Ts". Every Software component has, on its own data dictionary, a variable "Ts" .
However, when I try to place both Software components (as referenced subsystems) on a model (for Model in Loop simulation), I get the following error:
Symbol ‘Ts’ has multiple inconsistent definitions:

How can I calculate the Variance Inflation Factor (VIF) for a linear regression model
I have a long set of linear models developed from a space-filling DOE I ran. Many of the parameters in the DOE are correlated to different degrees and I’m interested in calculating the VIF of each parameter, and recalculating the model if the VIF for some parameters is high. I saw this code in another answer https://www.mathworks.com/matlabcentral/answers/1964984-tolerance-value-and-variance-inflation-factor-in-stepwiselm
% Define the predictors and response variable
X = [x1, x2, x3, x4, x5];
Y = y;
% Define the options for stepwise regression
options = statset(‘Display’,’iter’, ‘TolFun’, 0.01, ‘TolTypeFun’, ‘rel’, ‘PEnter’, 0.05, ‘PRemove’, 0.1);
% Run the stepwise regression with predefined multicollinearity threshold settings
mdl = stepwiselm(X, Y, ‘Criterion’, ‘bic’, ‘Upper’, ‘linear’, ‘Lower’, ‘constant’, ‘PEnter’, 0.05, ‘PRemove’, 0.1, ‘Verbose’, 1, ‘Options’, options);
% Check the multicollinearity
[vif, tolerance] = vif(mdl);
% Check for variable inclusion
included_vars = mdl.predictorNames(mdl.Coefficients.Estimate ~= 0);
However, I ran into a couple problems when trying to execute this snippet.
1) statset doesn’t take ‘PEnter’ or ‘PRemove’ as arguments. Removing those two arguments allowed that line to run.
2) stepwiselm doesn’t seem to take ‘Options’ as a valid argument
3) I can’t seem to find a function called vif that takes a linear model object as an argument
I have the curve fitting, data acquisition, deep learning, and statistics toolboxes installed. If there is another toolbox with applicable functions I can install that as well.I have a long set of linear models developed from a space-filling DOE I ran.
