This function file calculates roots of polynomial using Bairstow method

function [Root]=Bairstow(Coeff,initialGuess,MaxApproxError)

If a polynomial is ax^3+bx^2+cx+d=0 ,then input the coefficients in order in an vector as Coeff= [a b c d]

Input an initial guess i.e: initialGuess=-1

then input the maximum approximation error tolerance i.e: MaxApproxError=1e-9

The function will return the vector of all the roots of the polynomial.
