MATLAB error: “Undefined function or method 'time' for input arguments of type 'char'”

I wrote a modular MATLAB code which consists of several function files. I have no problem running my program. The problem is that once I try the code in debugging mode, I get the following error: "Undefined function or method 'time' for input arguments of type 'char'"

I don't understand what I did wrong.

I will appreciate your help.

And code.

Is it "time" or is it "times" ?

I found the problem!

The name of the first file consists of whitespaces. MATLAB file names must NOT include whitesapces!

Still, I think that MATLAB should give an error saying that file name is illegal. The existing message can't help anyone who encountered such a problem.

Thanks M B, This is exactly the same problem that I had. Like what you said there should not be any white space included.
