How to convert symbolic Jacobian to use it in lsqnonlin?

I have created Jacobian using Matlab build in function:

J = jacobian([functforJacobian],[p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 p11 p12 ]); This Jacobian is symbolic: J 53x12 112 sym Now I need to use this Jacobian in lsqnonlin:

opts = optimoptions(@lsqnonlin,'Jacobian','on'); [p,resnorm,res] = lsqnonlin(@myfun3,pguess,[],[],opts); but lsqnonlin do not understand sym. How should I convert my Jacobian to use it in lsqnonlin? Thanks for the help

There are some documentation examples on closely-related questions.

Symbolic gradients and Hessians using files.

Symbolic derivatives using function handles.

I'm sure that either of these examples will help.
