i have made the matlab source code to solve a differential equation. But when it is run, an error occurs on line 16. I don't know where the error is specifically located. If a

What is the full and exact text (everything displayed in red and/or orange in the Command Window) of the error and/or warning messages you receive when you run your code? The exact text of the messages may include information that will help us determine the problem or at least the next step to take in investigating the problem.
