Ok guys, for the iteration part of my broyden's method I have:
temp = x;
x = x - jac(x)\f(x);
s = x - temp;
y = f(x) - f(temp);
jac(x) = jac(x) + (y - jac(x)*s)*s'/(s*s);
now when I run this I get an error saying:
Error using * Inner matrix dimensions must agree. Error in broyden (line 32) jac(x) = jac(x) + (y - jac(x)*s)*s'/(s*s);
anyone know why this doesn't work?

jac(x) = jac(x) + (y - jac(x)*s)*s.'/(s(:).'*s(:));
or
jac(x) = jac(x) + (y - jac(x)*s)*s.'/norm(s).^2;
