Read Multiple Files with MATLAB

% Use UIGETFILE to allow for the selection of a custom file/files.

[filename, pathname] = uigetfile( ...

{'*.csv', 'All CSV-Files (*.csv)'; ...

'*.*','All Files (*.*)'}, ...

'Select File', 'MultiSelect','on');

% for one file, filename is a CHAR

% for multiple n files, filename is a 1xn CELL

% If "Cancel" is selected then return

if isequal([filename,pathname],[0,0])

return

% Otherwise construct the fullfilename and load the file.

else % data are given to data structures with the same names as files'

if iscell(filename) == 0; % only 1 file is chosen, filename is CHAR

File = fullfile(pathname,filename);

tempData = dlmread(File,',',11,0);

eval([filename '=tempData']);

else % multiple files are chosen, filename is CELL

[nRows, nFiles] = size(filename); % number of files

for i = 1 : nFiles

File = fullfile(pathname,char(filename(i)));

tempData = dlmread(File,',',11,0);

eval([cell2mat(filename(i)) '=tempData']);

end
