Very often, Matlab programs need to specify input files or images. Instead of giving the absolute path to that file we may make the user to browse and locate the file.
uigetfile is the function that can do that job. Here is an example.
disp('Select the Reference view');
[filename_ref,pathname_ref] = uigetfile('*.*','Select the Reference view');
if isequal(filename_ref,0)
disp('User selected Cancel')
else
disp(['Reference view: ', fullfile(pathname_ref, filename_ref)])
end
