using matlab, and fibonacci. i have included the picture of the function fofx

i believe problem should say of, not or the function fofx

Matlab is a program to do coding on, Golden Sequence is just Fibonacci

1. Write a function file to estimate the local maximum or minimum or the function fofx (use the last assignment one for testing) using Golden Section. Inputs are error, and the bounds of the initial interval function [y]=fofx(x) y=x^3+2x^2-111*x+108 end
