MATLAB CODE: Write a function with the header which calculates the partial derivative using the central difference method of function f with respect to x (ind). The central difference approximation of a function evaluated at x is: f = f (x + h)-f (x - h)/2epsilon and eps is used to permute x (ind) such that Solution The Code is here for function ------------------------------------------------------ function [df ] = myPartial(f,x,ind,eps ) %MYPARTIAL Summary of this function goes here % Detailed explanation goes here if ind==1 h=[eps;0;0]; elseif ind==2 h=[0;eps;0]; elseif ind==3 h=[0;0;eps]; end df=(f(x+h)-f(x-h))/(2*eps); end -----------------------------------------------------------------.
