Question

In this problem, you will be creating the function globalmin that uses MATLAB to approximate the x and y coordinate of the global minimum of a function within a given domain.
Inputs:

Func - an arbitrary function. eg. @(x) x.^2 + 4

xStart - The first x value in the function domain

xEnd - The last x value in the function domain

dx - The x spacing in the function domain.

Outputs:

xMin - The x-coordinate of the global minimum of the function within a given domain.

yMin - The global minimum of the function within a given domain.

Function Template

function [xMin,yMin] = globalmin(Func,xStart,xEnd,dx) %INSERT CODE end

Test Examples

[xMin,xMax] = globalmin(@(x) x.^3/3-x, -1.5, 1.5, 0.01) should return [1 -0.6667].

But [xMin,xMax] = globalmin(@(x) x.^3/3-x, -3, 3, 0.01) should return [-3 -6].
