The following code returns the error after it (ignore the "if true % code end" part):
if true
% code
end
%%%%%%%%%_CODE_%%%%%%%%%
playORquit=5
if playORquit ~= 1
fprintf('THANK YOU FOR PLAYING GUESS-TRON!\n');
fprintf('Here are your results...\n');
fprintf('Number of Trials: %d\n', trial);
end
%%%%%%%%%_ERROR_%%%%%%%%%
Index exceeds matrix dimensions.
Error in TEST_youcandelete (line 2)
fprintf('THANK YOU FOR PLAYING GUESS-TRON!\n');
%%%%%%%%%%%%%%%%%%%%%%%%%
How do I have those strings printed if 'playORquit' doesn't equal '1'

The entire if-block and enclosed statements execute without error for me with ‘playORquit=5’, and setting ‘playORquit=1’ results in their not being executed. I don’t see the error.

Nothing in the above code seems to point towards any error. You might have a variable called fprintf defined in your workspace, causing MATLAB to recognize fprintf to be a matrix you are trying to index into with your fprintf statement. Please check this and use a different variable name if you do have a variable called fprintf.

Thanks, I figured out that I made fprintf= to something by accident, so you were right. Thanks again.
