matlab function ---> find roots using fixed-point iteration

Fixed-Point iteration-Function fixed_point(p0, N) approximates the solution of an equation f(x) = 0, rewritten in the form x = g(x), which is a sub-function the user has to enter. the call to the function fixed_point(p0, N) returns the root of the eq

- for floating point to fixed point - seperate to integer and fraction part
