MATLAB: Save run a .m file and rename a file in a loop

fileMATLABsave

Hi. I want to ask. Is there anyway to run a .m file and rename a saved file by increment the number in the end of name, like version number in a loop, about 30 times. For example, I want to run A.m, and rename saved file results.mat as results1.mat. When another round, results.mat will rename as results2.mat, and so on.

Best Answer

oldname = 'results.mat';
for K = 1 : 30
   run('A.m');
   newname = sprintf('results%d.mat', K);
   movefile(oldname, newname);
end

Something like this might help:

function [oldFiles,newFiles] = splitFile(folder)
%SPLITFILE Finds files in folder, lists them and proposes new names
%   Detailed explanation goes here
dirList = dir(folder);
isDir = [dirList(:).isdir]; % to eliminate '.', '..' and any subfolders
oldFiles = {dirList(~isDir).name};
newFiles = replace(oldFiles, 'splitted_', '');
end

then use movefile to rename the files on disk.

I'm guessing you might also like to read the files into a workspace variable, where the variable name is constructed based on the source file name. One useful concept here is the associative naming for structs.

mystruct.name = readtable('myfile.txt');

works, and so also does

mystruct.('name') = readtable('myfile.txt');

This second form is quite useful here, because you can process the filename (using functions like replace() or regexp()) and use the filename to construct a fieldname that is appropriate.
