CPOTRS(3F)							    CPOTRS(3F)

NAME
     CPOTRS - solve 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

SYNOPSIS
     SUBROUTINE CPOTRS( UPLO, N, NRHS, A, LDA, B, LDB, INFO )

	 CHARACTER	UPLO

	 INTEGER	INFO, LDA, LDB, N, NRHS

	 COMPLEX	A( LDA, * ), B( LDB, * )

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.

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

     N	     (input) INTEGER
	     The order of the matrix A.	 N >= 0.

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

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

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

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

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