Hi, i have a problem with file.txt loop. I have to plot a series of datasets in different files (60). Is it possible to iterate the same procedure for each file in order not to define 60 variables? each dataset have different rows and columns numbers. Is it possible?

Yes, you need to create an a array of filenames and then use it to load them one by one. You don't have to manually define the array, you can use the dir function.

在 MATLAB Online 中打开

files = dir('*.txt') ;   % all the text files in the folder 
N = length(files) ;      % Total number of files 
% loop for each file 
for i = 1:N    
    thisfile = files(i).name ;
    % load the file 
    % do what you want
end
