gradient
Come on man ! I have to make the algorithm CG-Steihaug it's not easy. And I need the gradient of this function to make my algorithm works for functions f : R^2 -> R (my algorithm already works for functions f : R -> R) Please. -- View this message in context: http://r.789695.n4.nabble.com/gradient-tp4650734p4650790.html Sent from the R help mailing list archive at Nabble.com.
