You start your script with 'clear all', so no variables exist in your workspace. Then in your 5th line of code, you try to use y_1_0. What is this supposed to be? If it's a variable, it doesn't yet exist. If it's a function you wrote, MATLAB can't find it. The result is the error message you see.

I can duplicate the error here, too.

y_1_0

Unrecognized function or variable 'y_1_0'.
