It is shown in the red error text of your Command window

Give the command

dbstop if error

and run the code. If the place it stops is not a try/catch or error() call, then you have found the line with the problem.

If the place it stops is a try/catch or error() call, then give the command

dbstop if caught error

and run the code again. In some cases you might need to dbcont a few times to get to the correct line.

For example if you were having a problem with the objective function for fmincon then fmincon has try/catch statements to smoothly control for errors, and you would need to use the caught error construct to get to the original line.
