matrices - How is the preconditioned conjugate gradient algorithm related to the steepest descent method? - Mathematics Stack Exchange

There is a method to greatly simplify the preconditioned conjugate method into the steepest descent method, also known as gradient descent. I'm aware that the gradient is equal to $$2A^t(A\vec{x}
