Suggestions for Implementing Specific Generative AI Models in MATLAB
I am deeply interested in the field of generative AI, particularly in models like GANs (Generative Adversarial Networks). I’m looking to implement a simple GAN model for image generation in MATLAB. Could anyone provide specific guidance or best practices on how to design and train a GAN? Any suggestions regarding GAN architectures in MATLAB would also be greatly appreciated.

How to display the volume of a masked volume?
For a 3D image or a stack of 2D images stored in a matrix format (Nx, Ny, Nz), there is a corresponding mask image of the same size that defines a 3D volume within the 3D image. How can I display only this masked volume using volshow or other functions to visualize the volume?

Converging Errors in mathematical model of UAV launcher.
I have modelled a UAV launcher based on Alexander Khrulev’s paper "Analysis of Pneumatic UAV Launcher Parameters" 2023, which is an open-source paper available at ScienceDirect. I am getting different errors, but the most concerning is that my temperature drops to 0K during working, leading to errors as well as unrealistic behavior. The system consists of 4 differential equations which are tightly coupled, so I am having trouble locating exactly where the problem is. I suspect the problem is in gas dynamics modelling, especially in the intermediate "phi" and "leakage flow rate dm/dt" modelling in the pressure subsystem.

Issues solving a system of 2, second order, differential equations with ode45
Hello everybody,
I am starting with Matlab to solve a system of 2 differential equations, second order.
My code is below. It works, but the output is totally wrong.
This code is something taken on matlab help center and adapted to my problem, to help me start.
I have written things in the code "#comment " where it’s not clear to me.
Your help would be very helpful to me.
Thanks a lot in advance.

Plot lines with curves from csv file
Hi,
I have a csv/txt file that contains x,y,z and also the rotation center x and rotation center y data. The data are basically the coordinates of a path that a robot follows. The robot can make his path in a straight line and also in curves. How can I use the rotation center x and y coordinates in my data to plot the curves.
My current plot has only straight lines. But as you can see in the image attached, the actual path inlcudes curves around corners based on the rotation center x and y data. The following code is obviously not enough.

Writing tables within a for loop
Hi all,
I’m trying to make a for loop to process some EEG data. The final output is (1×96) for each participant which is finally working great, however, now I’m having issues writing the data/ looping through the participants. I’ve attached what the output looks like for one particpant as that is how far I can get. Below is what I’m trying to use unnsuccessfully. Any help is greatly appreciated!
SubjectNum = { ’01-02′ ’01-03′ };
resultsFileName = [fullfile(baseDir, ‘MATLAB_Output’, ‘DIVINE.75results.xlsx’)];
for k = 1:length(SubjectNum)
…. (whole bunch of steps)
RelativePowerResults = table(ID,channelsLabel,relativeDelta2,relativeTheta2,relativeAlpha2,relativeBeta2,relativeGamma2)
% unstack resulting in (1 row with 96 columns)
RelativePowerResults_Wide = unstack(RelativePowerResults,"relative"+["Alpha2","Delta2","Theta2","Beta2","Gamma2"],’channelsLabel’);
if k == 1
% First subject, with variable names
writetable(RelativePowerResults_Wide, resultsFileName, ‘Sheet’, 1, ‘Range’, RANGE{k});
else
% For subsequent subjects, write without variable names

defining upper and lower limits of a matrix
Hello all I have a smaller question and a larger question.
Small question: In the attached ‘viscosity_test.mat’ file is there a way to set the minimum value to 1e19? Is the process similar if I decide I want to set a maximum value?
Larger question: I am running a finite difference numerical model on an uploaded .png file (shown below). I believe the shape boundary is causing artificially low and high values to be output. Is there a way to troubleshoot this that doesn’t involve going through and manipulating the minimum and maximum values after the model runs? I can provide more details if that is unclear.
