MATLAB Stuck on Initializing… after 2025 Update
Hello everyone,
I was using MATLAB R2025a and found a notification about an available update. I clicked the update option, and it seemed to install successfully. MATLAB restarted automatically after the update, but now it gets stuck on the "Initializing" screen and never fully launches.
OS: Windows 11
MATLAB version: R2025a (after applying the latest update)
No error message appears, it just hangs at initialization.
I’ve tried restarting my computer, but the problem persists.
Has anyone experienced this issue? Are there recommended steps to fix it (e.g., clearing cache, resetting preferences, safe mode, or rolling back the update)?
Any suggestions would be greatly appreciated.

Solving diffeerntial equations numerically
I need to solve a set of ODEs from [Ts, Tend]. I want the solution to be output every dT. Within that interval dT, a vaiable step method should be used, but I need the solution every dT. I can use the codes in Matlab but this output every dT (without interpolation) is what I need.

Why am I receiving an abnormal exit error when running “mathworks.jmaab.jc_0790” from the Model Advisor?
Hello,
I am encountering an abnormal exit error when running the check mathworks.jmaab.jc_0790 in Model Advisor.
At first, when I run Model Advisor, the issue is handled normally as a warning. However, after I add a justification, this abnormal exit error occurs for that check.
I would like to understand:
Why does the check run normally as a warning at first, but fail after adding a justification?
Is this related to the justification data itself, a corrupted Model Advisor result, or an internal issue with the check?
Does this indicate a problem in the model, the Model Advisor environment, or a tool bug?
Are there any known limitations or version-specific issues related to mathworks.jmaab.jc_0790 and justification handling?
What steps should I follow to troubleshoot and identify the root cause?
Could you please advise on how to identify the cause and resolve this issue?
Thank you.
+ Additionally, for some Check IDs, the justification appears to be applied successfully in the GUI, but the corresponding JSON file is written in an invalid or corrupted state. How can this inconsistency be diagnosed and resolved?Hello,

How can I run the DREAM_Suite on mutliple data files without modifying the main code
I have this code that runs DREAM_Suite (attached) for data fitting and optimization using a Markov Chain algorithm. I can run this code on a single data file at a time, but I’d like to be able to run this optimization on multiple data files of the same kind, one after the other. Is it possible to do this through a simple modification in this "driver" script and withought having to modify/recompile the main code and associated functions in the DREAM package.

I’d also like to silence the postprocess output which is horendous as designed (muliple output figures and files, etc). I only need the file with the fit parameters (called therein ‘DREAM_ZS_output.txt’) as output from the individual data file fitting.

Faster way to save video from uifigure and geoglobe
Hi,
I need a faster way to get video output saved from a uifigure if possible.
I’m recording a camera fly using a geoglobe into an MP4 using VideoWriter. in my understanding the figure has to be a uifigure because geoglobe requires it. Each frame is captured with getframe(fig) and written with writeVideo.
For a ~30 min sim at 5 FPS (~10,000 frames at 1280×720) takes ~4 hours.
psuedo code:
fig = uifigure(‘Position’,[100 100 1280 720], ‘Visible’,’on’);
glo = geoglobe(fig, ‘Basemap’,’satellite’);
vid = VideoWriter(out_path, ‘MPEG-4’);
vid.FrameRate = 5;
vid.Quality = 85;
open(vid);
% …
% Loop:
for fi = 1:nFrames
% … compute cam_lat, cam_lon, cam_alt, cam_heading, cam_pitch, cam_roll …
campos(glo, cam_lat, cam_lon, cam_alt);
camheading(glo, cam_heading);
campitch(glo, cam_pitch);
camroll(glo, cam_roll);
drawnow
frame = getframe(fig);
writeVideo(vid, frame.cdata);
end
close(vid);
Things I’ve already tried and didn’t work:
FPS and Quality are already set to minimum desirables.
Switched the encoder to ‘Motion JPEG AVI’ but didn’t help.

What is the recommended ratio between mesh cell size and via port diameter when meshing a patch antenna geometry in MATLAB Antenna Toolbox for accurate simulation results?
I am simulating a patch antenna with a via port feed using MATLAB’s Antenna Toolbox. When meshing the antenna geometry, I need to understand the correct relationship between the mesh cell size and the via port diameter to ensure accurate simulation results.
Specifically:
– What should be the ratio between the linear mesh cell size and the via port diameter?
– Is there a recommended minimum number of mesh cells across the via diameter?
– Does this ratio affect convergence of S-parameters or radiation patterns more significantly?
Any guidance or references to best practices would be greatly appreciated.

Gas Properties Block – Corresponding REFPROP Variable Names
Hi,
I’m trying to populate the Gas Properties block in Simscape from REFPROP (using the approach provided by MATLAB here: MATLAB Interface for REFPROP and CoolProp – File Exchange – MATLAB Central).
However, there are some complexities in the naming of the variables that make populating the block difficult. When I call REFPROP, I use these variables from REFPROP (T,P,D,S,H,CP,VIS,TCX,KKT, and BETA) for the Matlab Gas Properties block variables. ARe these REFPROP names the correct ones to be calling? The last two are particularly confusing since alpha and beta can be used for each other in various documents…very strange.
I just want to make sure i"m calling the correct REFPROP variables for each MATLAB Gas Properties block variable.

How can I update multiple SVM classifier models in generated code without having to regenerate code in MATLAB R2025b?

However, every time I want to retrain and update the models, I need to regenerate the DLL, which is not practical for their deployment requirements. I need to be able to update the classifier models without regenerating the DLL during runtime.
Based on the "learnerCoderConfigurer" documentation, it is possible to update models without regenerating code using the "learnerCoderConfigurer" object and its update function.
