Hi,
I want to check if a folder has files starting with same name.
Eg in a folder, there are files ('test01.mat' , 'test02.mat', 'test03.mat' etc). they start with "test".
how can I check that? thanks.

% use the name of the folder you want to check:
folder = './';
% get info about the files in that folder whose name starts with 'test' and
% whose extension is .mat:
files = dir(fullfile(folder,'test*.mat'));
% see the files' names:
{files.name}
ans = 1×3 cell array
{'test01.mat'} {'test02.mat'} {'test03.mat'}
% and/or, see if there is more than one such file:
numel(files) > 1
ans = logical
1
% etc.
