NAME
       dsptrs.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dsptrs (UPLO, N, NRHS, AP, IPIV, B, LDB, INFO)
	   DSPTRS

Function/Subroutine Documentation
   subroutine dsptrs (characterUPLO, integerN, integerNRHS, double precision, dimension( * )AP,
       integer, dimension( * )IPIV, double precision, dimension( ldb, * )B, integerLDB,
       integerINFO)
       DSPTRS

       Purpose:

	    DSPTRS solves a system of linear equations A*X = B with a real
	    symmetric matrix A stored in packed format using the factorization
	    A = U*D*U**T or A = L*D*L**T computed by DSPTRF.

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     Specifies whether the details of the factorization are stored
		     as an upper or lower triangular matrix.
		     = 'U':  Upper triangular, form is A = U*D*U**T;
		     = 'L':  Lower triangular, form is A = L*D*L**T.

	   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.

	   AP

		     AP is DOUBLE PRECISION array, dimension (N*(N+1)/2)
		     The block diagonal matrix D and the multipliers used to
		     obtain the factor U or L as computed by DSPTRF, stored as a
		     packed triangular matrix.

	   IPIV

		     IPIV is INTEGER array, dimension (N)
		     Details of the interchanges and the block structure of D
		     as determined by DSPTRF.

	   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
