Question: Muller method

In Maple, is there `Muller` order can be directly used?

  I have a function such as p := proc (x) options operator, arrow; x^5+11*x^4-21*x^3-10*x^2-21*x-5 end proc, somebody wrote the method as r1:=muller(p,-13,-12,-11,.000001,100,r1); but maybe it is wrong.

I want to know how to use the method-muller.

Thank you very much.
