I need help for the numerical computation question, it requires to use matlab, the two functions that gonna help this question are post here. Thank you.

function fdjac (f, xO,y0) % FDJAC Finite-difference approximation of a Jacobian % Input: functionto be differentiated evaluation point (n-vector) value of f at x0 m-vector) x0 % Output approximate Jacobian (m-by-n) delta = sqrt(eps); % FD step size m=length(y0); n=length(X0); J = zeros(m,n); 1 = eye(n) ; for j 1:n end end
