Use the bisection method to find solutions in Matlab?

Question

I am trying to solve the following question:

Use the bisection method to find solutions accurate to within 10^−4 on the interval [−5, 5]

Answer 1

to define an equation that can be evaluated by feval, you need to define as a function.

Try defining fn as fn=@(x)(x^5-10x^3-4). This way you can use feval(fn,3).
