[filename, pathname] = uigetfile('*.txt', 'Open file .txt');
if isequal(filename, 0)
disp('File input canceled.');
else
filename = fullfile(pathname, filename);
[fid, msg] = fopen(filename,'r');
if fid < 0
error('Failed to open file "%s" because "%s"', filename, msg);
end
%at this point, do whatever it is you were going to do with the file
%identifier
end
I would suggest, though, that it would be easier to use
[filename, pathname] = uigetfile('*.txt', 'Open file .txt');
if isequal(filename, 0)
disp('File input canceled.');
else
filename = fullfile(pathname, filename);
data = readmatrix(filename, 'headerlines', 2);
end
