[FileName,pathname,d] = uigetfile('*.sp3','Choose the products','MultiSelect','on');
full_file_name(:,i) = fullfile(pathname,FileName(:,i));
Str(i,:) = fileread(full_file_name(i,:));
Here, when the lenght of first and second Str is not equal, I receive "Unable to perform assignment because the size of the left side is 1-by-35930605 and the size of the right side is 1-by-35909334" error. How I can store multiple Str while the theirs lenght are different?
