I have 2550 csv files. I have created a code that calculates a value for one of the files, but i need to loop over all 2550 and add together that value calculated for each csv file.

"I have 2550 csv files" &nbsp How to make a list of these files? Are they in a special folder? Are there some special characteristics in their names?

The csv files and .m file are all in the same folder. All the csv files are called Scan_* where * is a number

This is one approach, (which I like)

folderspec = 'c:\same\folder';
file_glob  = 'Scan_*.csv';
sad = dir( fullfile( folderspec, file_glob ) );
for jj = 1 : length( sad )
    fid = fopen( fullfile( folderspec, sad(jj).name ), 'r' );
    cac = textscan( fid, ... );
    fclose( fid );
    ...
    ...
end
