class	CH_Matrix_Classes::PCG
	Preconditioned Conjugate Gradient method for solving Ax=b with (symmetric) positive definite matrix A and positive definite preconditioner M1 where the preconditioned system is A'x'=b' with A'=M1^{-.5}AM1^{-.5}, x'=M1^{.5}*x and b'=M1^{-.5}b. System matrix and preconditioner are provided by a CH_Matrix_Classes::IterativeSystemObject. More...
