NAME
       spptrs.f -

SYNOPSIS
   Functions/Subroutines
       subroutine spptrs (UPLO, N, NRHS, AP, B, LDB, INFO)
	   SPPTRS

Function/Subroutine Documentation
   subroutine spptrs (characterUPLO, integerN, integerNRHS, real, dimension( * )AP, real, dimension( ldb, * )B, integerLDB, integerINFO)
       SPPTRS

       Purpose:

	    SPPTRS solves a system of linear equations A*X = B with a symmetric
	    positive definite matrix A in packed storage using the Cholesky
	    factorization A = U**T*U or A = L*L**T computed by SPPTRF.

       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.

	   AP

		     AP is REAL array, dimension (N*(N+1)/2)
		     The triangular factor U or L from the Cholesky factorization
		     A = U**T*U or A = L*L**T, packed columnwise in a linear
		     array.  The j-th column of U or L is stored in the array AP
		     as follows:
		     if UPLO = 'U', AP(i + (j-1)*j/2) = U(i,j) for 1<=i<=j;
		     if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = L(i,j) for j<=i<=n.

	   B

		     B is REAL 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
