How can I programmatically set the modeling option parameter for a Simscape Battery block in MATLAB to "Instrumented | Show thermal port" to display both the SOC and thermal ports?
I tried using get_param to retrieve the parameters of the battery block, but I couldn’t find any related to the modeling options (SOC or thermal ports).

Currently, I am working on an app that can successfully write 4 columns of data to a text file in a user-defined file location, at the push of a button. I am accomplishing this task using the following code:
% Button pushed function: ExporttotxtButton
function ExporttotxtButtonPushed(app, event)

[fn,pn] = uiputfile(‘.rdf’,’RoadProfile_bumpy_fl.rdf’,’RoadProfile_bumpy_fl.rdf’);

if isnumeric(fn) % user canceled
return % return early
end
% write the table to the user-specified file
writematrix(app.UITable.Data,fullfile(pn,fn),’Delimiter’,’tab’,’FileType’,’text’);
However, I have a very long string of text (about 47 lines of text…not included here to save space) that I would like to include as a header in the generated text file. The goal is to have the end result be a text file that already has the header populated with a standard 47 lines of text, and then write the matrix data below the header as I am already doing. I have tried using the following:
fprintf(fullfile(pn,fn),’%sn’,[‘long_string_of_text..’ …
‘creating new line each timen’…]
But, this doesn’t seem to work. Any help would be much appreciated. I can post the full text that I want to include in the header if that is necessary.

I´m doing a code to generate a system composer report with sequence diagrams, but when i run the code, i get the error: Unable to open file ‘C:UsersuserOneDriveDocumentsMATLABimage.png for writing. Check write permission. I checked that path and i do have writing permission, and i try running matlab as admin, but i get the same error. The tricky part is, if I run a simple code using the imwrite comand to save an image in that path (before running the report generator code i have), it works well and it writes an image there, but as soon as i run the repor generator code, i get the error, and if again, try to use the imwrite command (that previously worked) it throws the same error that said i don´t have write permission, but it had worked moments ago.

Hey,
I have a very large model and initially I have given random names to signal labels. Now I have somewhat achieved what I wanted wth my model, and I wish to make some minor modifications such as changing the signal labels. I do not wish to do it manually.
I was trying to change the signal labels for signals coming out of bus selector. I am using the
find_system and set functions to do this task but not able to do so. Issue is that bus selector does not find the new signal name.
I am able to change the name manually without any issue.

I transform RGB images to indexed images with cmunique. Some of the indices in the indexed image are 0. It is not mentioned in the help for cmunique, but there is a contradictory statement in the help for rgb2ind, bold in the abbreviated citation below:
"[X,map] = rgb2ind(RGB,n) : Indexed image, returned as an m-by-n matrix X of nonnegative integers. If the length of map is less than or equal to 256, then the output image is of class uint8. Otherwise, the output image is of class uint16. n must be less than or equal to 65,536.
The value 0 in the output array X corresponds to the first color in the colormap."

In my case, the length of smallest color map is of the order of ~1500, so uint16 indices are expected. What do I do with elements of X that are 0 (zero), is there a way to prevent this happening?
