Hi all,

I have to load some .txt files from different subdirectory. The files name is the same for all of them, only the subdirectory's name changes. I have wrote this code but I have a problem: at each cycle the for loop overwrite the imported matrix. How Can I rename differently the imported matrices? Thx a lot!

SS=string(ones(N,1));     %declare matrix
s=(pwd);                  %check path
for i=1:N
    
    SS(i,1)= sprintf('Risultati%d', i);
    ss(i)=strcat(s,{'\'},SS(i),{'\'},{'disp.out'});
    importdata(ss(i));             %%i can use also load function
end

Use indexing to store it in an array:

MATLAB most useful and powerful feature is its ability to work with arrays. It is better to store the imported matrices in a single array and keep appending the matrices as each file is being imported. You can access a matrix from a particular file by proper indexing.
