Combining structs into one struct.
Hello, I have several structs that I would like to combine together into one. The issue I find is that the data for some reasons gets completely jumbled. Each time the file runs, the columns from one struct become a part of another and I cannot figure out why
CombineGLMParam(‘2_2_2’, ‘2_3_2′,’2’)
CombineGLMParam(0, ‘2_5_1′,’2’)
function CombineGLMParam(bat1,bat2,bat)
%Combine GLM parameters by putting in the bat and the file. If bat1 is not 0, open the bat1 file and create a file GLM bat.
% If it is 0, open the GLM Bat file and append the bat 2 file to GLM.

How to set Simulink block parameters using an absolute model path
I am calling a simulink model out of a MATLAB script, but this model is located in a different directory (not in the working directory).
This model can be executed by using the "sim" command in combination with the absolute path, e.g:
sim("C:UsersMATLABmyModel.slx")
Now I want to change the parameter of a "Contant" block when calling the simulation.
The functions "set_param" seems only to work with a model handle which was created by a model being in the current working path.
% name of model
mdl = "myMdl";
% name of the block
blk = "myConstBlk";
% Serch path
path = strcat(mdl, "/", blk);
% set parameter of Const
set_param(path, "Value", "5");
When performing the same action, but with an absolute path, this is not working anymore.
% name of model
mdl = "C:UsersMATLABmyModel.slx";
% name of the block
blk = "myConstBlk";
% Serch path
path = strcat(mdl, "/", blk);
% set parameter of Const
set_param(path, "Value", "5");
Invalid Simulink object name: ‘C:UsersMATLABmyMdl.slx/myConstBlk’.
Even if the model is loaded by:
h = load_system(mdl); %mdl is the absolute path
the handel "h" could not be used in the set_param function.
So therefore the qustion:

Monte Carlo integration (hit or miss) to find the area of a circle of radius R
Hi everyone. Trying to solve an old exam topic regarding Monte Carlo integration, I wrote the following code for which I based it on a code from a professor in the C language. For R = 1 it worked so I assume I did it correctly. Then I tried R > 1 and the results were wrong compared to the formula πR^2 so I tried a few modifications by trial and error method. I fixed the problem and it seems to works correctly but there is a modification that I don’t understand. If you could help me understand this it would be great. Thank you in advance.

Understanding basics of struct?
Hello,
A beginners short story with 3 and a half Questions:
I want to get a list of all filepath of filenames in a folder (?).
For that I’m using dir which creates a struct (so far so good).
Now I want to save the first colum with the filenames as a cell array (?)
Solved this by using struct2cell .
But is there a way to export a single colum (or even a defined range of that colum) ?
I was also thinking an easy for loop would solve that but…
I’m struggeling to get the length of the struct ?
And…
Is there an elegant way to sort names in the struct in a "natural way" (1,2,3,…,11,12 instead of 1,11,12,2,3,…) ?
Big Thanks!!!Hello,

How to sum the product between a matrix and 2 vectors
I need to solve a system of differential equation written as:
For each equation I should solve a summation like:
where K_Br is a matrix previously calculated and n is a vector as the solution of the differential equation system.
For example, for i=3:
I wrote the system of differential equation as:
function ndot = System_ni (t,n)
ndot = zeros(M,1);
ndot(1) = -n(1)*sum(K_Br(1,1:M)*n(1:M));
for i = 2:M
ndot(i) = 1/2*sum(K_Br(1:i-1,i-1:1)*n(i-1:1)*n(1:i-1))-n(i)*sum(K_Br(i,1:M)*n(1:M));
end
end
but summation seems not to work.
Thank you in advance for any help.I need to solve a system of differential equation written as:
For each equation I should solve a summation like:
where K_Br is a matrix previously calculated and n is a vector as the solution of the differential equation system.
For example, for i=3:
I wrote the system of differential equation as:
function ndot = System_ni (t,n)
ndot = zeros(M,1);
ndot(1) = -n(1)*sum(K_Br(1,1:M)*n(1:M));
for i = 2:M
ndot(i) = 1/2*sum(K_Br(1:i-1,i-1:1)*n(i-1:1)*n(1:i-1))-n(i)*sum(K_Br(i,1:M)*n(1:M));
end
end
but summation seems not to work.

C2000 Delfino does not receive code when being powered externally
I am trying to make the LED on my F28379D blink as proof that I can flash code to the board. I have an old model in 2022a which has always compiled fine and works when being powered externally with all of the required hardware attached. I am migrating to 2024b and am trying to make the model run as such. When I power the delfino from the USB with nothing else attached it flashes fine and the LED blinks, when I take the exact same model and and run it on a board that is powered externally and has some other hardware attached (works for 2022a) simulink says that it copiles fine and uploads fine but doesn’t actually blink the led or run anything else.
Any help/ideas is greatly appreciated.I am trying to make the LED on my F28379D blink as proof that I can flash code to the board.

Viewing Live Script in viewer.mathworks.com
Hi –
I am the steward for some open source projects, and we want to be able to include links to view the output of Matlab Live Scripts on the web.
There are several links like this on the File Exchange, for example one such link from https://www.mathworks.com/matlabcentral/fileexchange/134991-deepinterpolation-matlab is:
https://viewer.mathworks.com/?viewer=live_code&url=https%3A%2F%2Fwww.mathworks.com%2Fmatlabcentral%2Fmlc-downloads%2Fdownloads%2F84c22101-bffc-435a-910c-b0c7dcd5b386%2F4dd1b338-1032-45d1-b894-d1779b6d28f2%2Ffiles%2Fexamples%2Ftiny_ephys_inference.mlx&embed=web
The trouble is that this links to a specific file in a specific version, and I’d like to be able to grab a Live Script from GitHub so that as the script is updated on GitHub, the viewing link always points to the latest version. Right now, I’d have to know the encoded path in FileExchange that will be generated when it updates the File Exchange version from GitHub.
But I don’t seem to be able to get the viewer to read from GitHub. It is possible that I have a path error here but I have redone this a couple times and I always see "We’re sorry, but something went wrong". So perhaps it’s not legal to pull scripts from other places?

The broader issue is, is there any recommended way to keep a link to the "current" version instead of to a specific version?

Reducing a dataset’s dimensions with PCA and projecting it onto a graph.
Hi all,
Like the title says, I’d like to take a large dataset X of m by n size and reduce it’s dimensions to m by 2 length, and from there project it onto a 2D plane where the axis are the two main principal components of X. Is the below code enough, or have I missed a step?
[a,b] = pca(X);
b = b’;
plot(b(1,:),b(2,:),’.’);
From what I understand, taking the two columns of b gives me the two principal components that tell us the most about X’s structure, whilst having reduced it’s dimensions down. I’m basing this on the <http://www.nlpca.org/pca-principal-component-analysis-matlab.html code I found here,> but I just wanted to check I had it correct.Hi all,
