Hi,
I am using below code to import data from .dat and .xlsx files. How I can save the imported data in two matrices. I mean .dat imported data save to matrix A and .xlsx imported data save to B matrix
[filename, pathname, filterindex] = uigetfile( ...
{ '*.mat','MAT-files (*.mat)'; ...
'*.slx;*.mdl','Models (*.slx, *.mdl)'; ...
'*.*', 'All Files (*.*)'}, ...
'Pick a file', ...
'MultiSelect', 'on');
Thanks

Because you have MultiSelect on, the returned filename will be a cell array of strings. You can loop over those taking one at a time and dealing with it:
for K = 1 : length(filename)
thisfilename = filename{K};
[~, ~, this_ext] = fileparts(thisfilename);
if strcmpi(this_ext, '.mat')
it is a .mat file. Process it
elseif strcmpi(this_ext, '.xlsx')
it is a .xlsx file, process it
else
oh oh, how did this happen? What to do now?
end
end

The lines "it is a .mat file. Process it", "it is a .xlsx file, process it" and "oh oh, how did this happen? What to do now?" are intended to be places that you replace with code specific to what you want to do with your files.

Hi,
Thank you for your reply. I just want to import data using uigetfile and write the imported files in matrices so I can use it in my code?
