If you have a Symbolic Math Toolbox license, you can work along the lines of this example. Or of this example, which uses files rather than function handles.

Thanks for your answers! When n is small,it is a not bad solution,however, when n is large,it will spend so much time, I need to get iteration solution, it may not be a good ideal, and function matlabFunction can convert it to a function handles, but it runs so much time. Best wish to you!
