NAME
       dpotrs.f -

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

Function/Subroutine Documentation
   subroutine dpotrs (characterUPLO, integerN, integerNRHS, double precision, dimension( lda, * )A, integerLDA, double precision, dimension( ldb,
       * )B, integerLDB, integerINFO)
       DPOTRS

       Purpose:

	    DPOTRS solves a system of linear equations A*X = B with a symmetric
	    positive definite matrix A using the Cholesky factorization
	    A = U**T*U or A = L*L**T computed by DPOTRF.

       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 DOUBLE PRECISION array, dimension (LDA,N)
		     The triangular factor U or L from the Cholesky factorization
		     A = U**T*U or A = L*L**T, as computed by DPOTRF.

	   LDA

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

	   B

		     B is DOUBLE PRECISION 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
