OK, so you most likely have a problem with your x variable in the calculation of the residuals.That x is coming from somewhere, it may well be called something different outside of the function definition. It's being passed to that function somewhere above. You need to make sure you're not doing something wrong in the way you're defining your x (looks like probably the design matrix for your least squares problem).

Hi Natasha, I'm sorry without having the MATLAB code and data. I can't specifically tell you how to solve the problem.
