Hello,

I don't really know how to write this question properly. I've spent the past few hours googling and I did not find a good solution. Most answers are "don't do this" - but let me explain.

I've got (not made by me!) a folder with maany subfolders and in each subfolder there are 4 different .m files - each file is a single (quite large, around 500x500) matrix.

All of the files follow some naming logic, but they are terrible to use in MATLAB.

See picture:

In the end I need to load each .m file, cut the size, and combine into a single matrix. I know how to cut the size and combine, but I don't know how to automate the import.

So what I want:

...to add this file as an input to the classification learner, which only accepts one single matrix?

The matrix needs to be in a specific order, which is sadly not alphabetic - but the order the folders were created in - Date.

I loaded all .m files up in the workspace and created a struct, but the order of the entries is wrong.

I would be happy if I just get this done, with whatever "not reccomended" or unrobust or ugly way.

I'm fine with:

the idea of using placeholders in a for-loop for the multiple variables - is this possible?

importing all files and renaming them 1:1:length(x) and then edit them in a loop - how?

How would you go about this problem?

"How would you go about this problem?"

I don't see why you need to rename any files or use "placeholders in a for-loop for the multiple variables" (whatever that means). Why not do the obvious:
