Nonlinear Conjugate gradient method as callable subroutine.

Main program for running the conjugate gradient methods described in the paper:

Gilbert, J.C. and Nocedal, J. (1992). "Global Convergence Properties of Conjugate Gradient Methods", SIAM Journal on Optimization, Vol. 2, pp. 21-42.

A web-based Server which solves unconstrained nonlinear optimization problems using this Conjugate Gradient code can be found at:

Written by G. Liu, J. Nocedal and R. Waltz October 1998

modified to be a callable subroutine by Philip A Browne Jan 2015

Parameters

[in]	method	which CG method to use
[in]	n	the dimension of the state vector
[in]	epsin	the value of EPS to be used as convergence tolerance
[in,out]	x	on entry the initial guess, on exit is the optimized state vector
