Programming a function for use in another script

I've programmed a script to run multivariate Newton's method on a non-linear function. It's usage is:

function [X]=mynewtonA(fname,x0,maxIts,tol)

fname represents the function I want to program.

I'm trying to program the following function for use in this existing function:

I'm not sure how to do this. So basically, what should be code be to produce this function in a new file that I can then call upon in my existing script?

You could write an mfile for this function and pass a handle to that function to mynewtonA. See Calling a Function Using it's Handle.

You could also create an Anonymous Function

f=@(x) [x(1)-sin(x(2));x(1).*sqrt(abs(x(2))) ];

and pass that directly.
