Solving nonlinear set of equation using lsqnonlin

I'm writing a code to solve nonlinear set of equations using lsqnonlin. But I'm getting the error: "Nonscalar arrays of function handles are not allowed; use cell arrays instead." I don't know how to go about it. Please help. Attached is the matlab code and required files.

You cannot generate the different residual terms in the least squares objective with separate functions. A single function, supplied by you, must be used to generate all N residuals. The objective function that you supply must return the residuals in an Nx1 vector.

Then how else can I solve the same problem?

I believe I already told you. Generate the residuals with 1 function, instead of many.
