Exporting image-generated geometry in matlab to FEA compatible format
Hello, I am doing an undergraduate thesis, and I like to implement MATLAB in some of the analysis.
The query is, how to export a file generated as an image in a code, to a format compatible with FEA (Finite element analysis).
The goal is to find the temperature profile in this slag pot geometry, which is a truncated cone.
So, once having the compatible geometry I can use matlab pdegplot and some commands related to find the temperature profile.
The code was generated by AI (Claude).

Calling a function with no arguments
Hi All,
In my program , I’m trying to call a function with some input arguments but no outputs as I’m using this function for the purpose of plotting.
How should its syntax look like?
[ ] = function_name( var1,var2,var3) // This line is giving me erorr : Assigning an output to an empty array is not supported.
Please suggest me a way to handle this error.

Why I can’t save my data in a .mat when using WebAppServer?
My application is used to take a test to several people.
At each instance, Scores.mat is opened. It contains the structure Scores which stores the scores of the previous participants. The number of participants is retrieved. The new participant takes the test and the new scores are added to the strucure Scores. At the end of the test, the structure Scores is saved in Scores.mat, and so on.
% Load the scores table
load Scores.mat
app.Scores = Scores;
% Increment the participant index
app.idxParticipant = length(app.Scores) + 1;
% (…)
% Save scores (code has been modified for better clarity)
app.Scores(app.idxParticipant).Model(1) = app.EditField.Value;
app.Scores(app.idxParticipant).Model(2) = app.EditField_2.Value;
app.Scores(app.idxParticipant).Model(3) = app.EditField_3.Value;
% (…)
% Save listener scores
Scores = app.Scores;
save(‘Scores.mat’,’Scores’)
Locally, everything runs well, of course. But when I test the Matlab WebApp, the very last step doesn’t work: the structure Scores is not saved in Scores.mat and there is no errors in the logs.
Scores.mat is well embedded in the WebApp as I am able to open it and retrieve the Scores structure. The structure is well updated, I’ve checked it, but I am not able to save the updated structure back into Scores.mat.
I hope someone could help me here. Many thanks!My application is used to take a test to several people.

Correspondence between student name and Learner ID in Matlab Grader and Moodle
We are using Matlab Grader in a Moodle platform. Though we are able to detect and give feedback for most of the common errors made by our students, teachers often need to revise the code of individual students. The correspondence between Matlab Grader’s Learner ID and student’s names in Moodle must be stablished somewhere. Can we access this information? Asking our students to submit their Solution ID, a solution that I’ve seen in several of the questions posted to this community, is just not an option. The procedure ought to be automatized somehow, probably by our Moodle platform managers, but is this possible?

Untraining the SalsaNext model Architecture
I used the following repository to evaluate my data (https://github.com/matlab-deep-learning/pretrained-salsanext), but it loads a pretrained SalsaNext model. I would like to know whether it is possible to untrain the model, or to train it from scratch without creating the layergraph (Since this model involves a large number of layers, and the work seems to be cumbersome, and error-prone).

I want to plot the auto correlation function for 15 numbers without using the inbuilt function. My series is P=[ 47,64,23,71,38,64,55,41,59,48,71,35,57,40,58 ] and the plot should be autocorrelation function vs lags.
I want to plot the auto correlation function for 15 numbers without using the inbuilt function.
My code is as follows:
P=[ 47,64,23,71,38,64,55,41,59,48]; %%,71,35,57,40,58 ];
N=length(P);
Q=P(1:N);
R=P(1:N);
N1=length(Q);
N2=length(R);
u=mean(P);
sum= ((Q-u)*(R-u).’);
covar0=sum/N1;
for k=1:N-1 %% k is no. of lags and its max value can be 14 here
Q1=P(1:N-k); %% Splitting the series into 2 series separated by lag k
R1=P(1+k:N);
N1_1=length(Q1);
N2_1=length(R1);
sum1= ((Q1-u)*(R1-u).’);
covark=sum1/N;
acf=covark/covar0;
acf;
end
But after execution of the loop,I am getting acf value only for last value of k, which rather should have been an array for values of k=1 to 14.

Different filters for pretrainned network
if i have a group of images and i filtered all of them with 8 different filters , is there a way or method or a published something or calculate a fator to know me which filtered group is best with specific pretrainned transfer learning network for classification task using matlab without training the network with each group of filtered imagesif i have a group of images and i filtered all of them with 8 different filters , is there a way or method or a published something or calculate a fator to know me which filtered group is best with specific pretrainned transfer learning network for classification task using matlab without training the network with each group of filtered images if i have a group of images and i filtered all of them with 8 different filters , is there a way or method or a published something or calculate a fator to know me which filtered group is best with specific pretrainned transfer learning network for classification task using matlab without training the network with each group of filtered images filtering pretrainned MATLAB Answers — New Questions
How to display Chart diagram in a report, using report generator?
Hi,
I have a problem with the visualization of Chart diagram and related properties in my model.
I using this code line (in a matlab script) to search all the subsystem object (including chart):
allsubsysObj = modelObj.find(‘-isa’,’Simulink.SubSystem’,’-or’,’-isa’,’Simulink.ModelReference’,’-depth’,1);
The script find the number of element that i’m expected (2 chart and 2 subsytem) but when i tried to put the diagram figure i obtained the inner content of the subsytem and the chart.
auxpara = CenterDiagram(Diagram(allsubsysObj(1)),R);
Cap = Text(strcat("Figure ",num2str(ChCounter),".",num2str(FigCounter),": ",allsubsysObj(1).Name," subsystem"));
Cap.Style = [{FontSize(Str.CapFontSize)},{Color(Str.CapColor)},{Bold(true)},{HAlign(Str.CapAlign)}];
FigCounter = FigCounter + 1;
subsec.add(auxpara);
subsec.add(Cap);
subsec.add(LineBreak());
