Folder = tempdir; % Define accordingly
FileList = dir(fullfile(Folder, 'text*.mat'));
NewFile = fullfile(Folder, sprintf('text%d.mat', numel(FileList) + 1));
This fails, if you delete some of the files afterwards. Then this helps:
NameList = natsort({FileList.name});
LastIndex = sscanf(NameList{end}, 'text%d.mat'));
NewFile = fullfile(Folder, sprintf('text%d.mat', LastIndex + 1));
Or prefer:
nowStr = datestr(now, 'yyyy-mm-dd_HHMMSS');
NewFile = fullfile(Folder, ['text', nowStr, '.mat']);
But remember that this fails, if you create more than 1 file per second or during the change of the daylight-saving-time.
