I have several csv files in one folder and I want to convert them all to .mat format?

Is it possible to do that at once?

Folder   = 'D:\YourFolder';
FileList = dir(fullfile(Folder, '*.csv'));
for iFile = 1:numel(FileList)
    % [TYPO FIXED]:  [name, ext] ==> [~, name, ext]
    [~, name, ext] = fileparts(FileList(iFile).name);
    data = readtable(fullfile(Folder, [name, ext]));
    save(fullfile(Folder, [name, '.mat']), 'data');

This suggestion does it during the creation already. Then you do not have to do it again. But the code looks similar to the one of my answer:

Folder   = 'D:\YourFolder';
FileList = dir(fullfile(Folder, '*.mat'));
for iFile = 1:numel(FileList)
    FileData = load(fullfile(Folder, FileList(iFile).name));
    data     = FileData.data;
    data(1, :) = [];
    save(fullfile(Folder, [name, '.mat']), 'data');
end
