You need to pass it a string
for k = 1 : 10
message = sprintf('k = %4d\n', k);
uiwait(msgbox(message));
% You can use fprintf() instead if you don't want to prompt the user.
fprintf(message); % Goes to command window.
end
Or better yet, use questdlg() so the user can have an opportunity to break out of your 1000 iteration loop:
for k = 1 : 10
message = sprintf('k = %4d\nContinue?', k);
reply = questdlg(message, 'Continue', 'OK', 'Cancel', 'OK');
if strcmpi(reply, 'Cancel')
% User said Cancel, so exit.
break;
end
end
I used k as a loop variable because you're not supposed to use i or j - they're the imaginary variable.
