SYNOPSIS
   Functions/Subroutines
       subroutine ssytrs2 (UPLO, N, NRHS, A, LDA, IPIV, B, LDB, WORK, INFO)
	   SSYTRS2

Function/Subroutine Documentation
   subroutine ssytrs2 (characterUPLO, integerN, integerNRHS, real, dimension( lda, * )A, integerLDA, integer, dimension( * )IPIV, real, dimension(
       ldb, * )B, integerLDB, real, dimension( * )WORK, integerINFO)
       SSYTRS2

       Purpose:

	    SSYTRS2 solves a system of linear equations A*X = B with a real
	    symmetric matrix A using the factorization A = U*D*U**T or
	    A = L*D*L**T computed by SSYTRF and converted by SSYCONV.

       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.

	   A

		     A is REAL array, dimension (LDA,N)
		     The block diagonal matrix D and the multipliers used to
		     obtain the factor U or L as computed by SSYTRF.

	   LDA

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

	   IPIV

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

	   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).

	   WORK

		     WORK is REAL array, dimension (N)

	   INFO

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