Talk:Conjugate gradient method

From Wikipedia, the free encyclopedia

[edit] First few lines are messy

I think that it is more correct to say: Conjugate gradient is a line search method for optimizing a function of several variables. It is often applied to solve linear systems of equations. (save the details for later)

This article is too condensed. Could you please give some more explications? Where do the alphas come from? What does mean: "This suggests taking the first basis vector p1 to be the gradient of f at x = x0, which equals -b" ? Sorry, I dont understand what you are talking about.
