HELP - Newton's Method
Hi everyone, Is there a way to evaluate vector functions in Matlab? Eg where x = [x1;x2;x3], F(x) = [sin(x1) + 3*x2; x1^2 + x2^2 - x3; cos(x3)] Can I calculate F(x0) for some initial guess vector and use this in an iterative formula? Apparently it's not possible to make inline vector functions, is there another m... 25 Apr 2010 12:08
