Importing matrices in text files and creating a structure with 100 entries

1 view (last 30 days)
Hello there,
I was hoping that somebody could perhaps help me out with a problem that I have. I'm only learning how to use matlab.
I have 100 4x4 matrices in .txt files in a folder.
How could I import them and create a structure with 100 entries and in each entry there would be one matrix.
The reason I ask is because I'm trying to get the average of these matrices and this post provides a solution if the matrices are in this format.
Thank you for your help
Regards
John

Also note, that if they're all the same size, you could stack them along the third dimension and then take the mean of the first and second dimension which would leave you with each matrice's mean.

Hi again,
Honestly I haven't been able to get it to work
This is the code I'm using
C = cell(100,1);
for ii = 1:100
C{ii} = importdata(['matrix' num2str(ii) '.txt']) ;
end
but I'm getting this error
??? Error using ==> importdata at 123
Unable to open file.
The files are just text files each containing a 4x4 matrix
Could you offer any further suggestions?
Thank you
