NAME
       cpotrs.f -

SYNOPSIS
   Functions/Subroutines
       subroutine cpotrs (UPLO, N, NRHS, A, LDA, B, LDB, INFO)
	   CPOTRS

Function/Subroutine Documentation
   subroutine cpotrs (characterUPLO, integerN, integerNRHS, complex, dimension( lda, * )A, integerLDA, complex, dimension( ldb, * )B, integerLDB,
       integerINFO)
       CPOTRS

       Purpose:

	    CPOTRS solves a system of linear equations A*X = B with a Hermitian
	    positive definite matrix A using the Cholesky factorization
	    A = U**H*U or A = L*L**H computed by CPOTRF.

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     = 'U':  Upper triangle of A is stored;
		     = 'L':  Lower triangle of A is stored.

	   N

		     N is INTEGER
		     The order of the matrix A.  N >= 0.

	   NRHS

		     NRHS is INTEGER
		     The number of right hand sides, i.e., the number of columns
		     of the matrix B.  NRHS >= 0.

	   A

		     A is COMPLEX array, dimension (LDA,N)
		     The triangular factor U or L from the Cholesky factorization
		     A = U**H*U or A = L*L**H, as computed by CPOTRF.

	   LDA

		     LDA is INTEGER
		     The leading dimension of the array A.  LDA >= max(1,N).

	   B

		     B is COMPLEX array, dimension (LDB,NRHS)
		     On entry, the right hand side matrix B.
		     On exit, the solution matrix X.

	   LDB

		     LDB is INTEGER
		     The leading dimension of the array B.  LDB >= max(1,N).

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
		     < 0:  if INFO = -i, the i-th argument had an illegal value
