In this paper, we have discussed and investigated an extended PR-CG method which uses function and gradient values. The new method involves the extended CG-methods and have the sufficient descent and globally convergence properties under certain conditions. We have got some important numerical results by improving a standard computer program compared with Wu and Chen (2010) method in this field.
