NAME

       sptts2.f -

SYNOPSIS

   Functions/Subroutines
       subroutine sptts2 (N, NRHS, D, E, B, LDB)
	   SPTTS2

Function/Subroutine Documentation
   subroutine sptts2 (integerN, integerNRHS, real, dimension( * )D, real, dimension( * )E, real, dimension( ldb, * )B, integerLDB)
       SPTTS2

       Purpose:

	    SPTTS2 solves a tridiagonal system of the form
	       A * X = B
	    using the L*D*L**T factorization of A computed by SPTTRF.  D is a
	    diagonal matrix specified in the vector D, L is a unit bidiagonal
	    matrix whose subdiagonal is specified in the vector E, and X and B
	    are N by NRHS matrices.

       Parameters:
	   N

		     N is INTEGER
		     The order of the tridiagonal 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.

	   D

		     D is REAL array, dimension (N)
		     The n diagonal elements of the diagonal matrix D from the
		     L*D*L**T factorization of A.

	   E

		     E is REAL array, dimension (N-1)
		     The (n-1) subdiagonal elements of the unit bidiagonal factor
		     L from the L*D*L**T factorization of A.  E can also be regarded
		     as the superdiagonal of the unit bidiagonal factor U from the
		     factorization A = U**T*D*U.

	   B

		     B is REAL array, dimension (LDB,NRHS)
		     On entry, the right hand side vectors B for the system of
		     linear equations.
		     On exit, the solution vectors, X.

	   LDB

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

	    matrix whose subdiagonal is specified in the vector E, and X and B
	    are N by NRHS matrices.

       Parameters:
	   N

		     N is INTEGER
		     The order of the tridiagonal 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.

	   D

		     D is REAL array, dimension (N)
		     The n diagonal elements of the diagonal matrix D from the
		     L*D*L**T factorization of A.

	   E

		     E is REAL array, dimension (N-1)
		     The (n-1) subdiagonal elements of the unit bidiagonal factor
		     L from the L*D*L**T factorization of A.  E can also be regarded
		     as the superdiagonal of the unit bidiagonal factor U from the
		     factorization A = U**T*D*U.

	   B

		     B is REAL array, dimension (LDB,NRHS)
		     On entry, the right hand side vectors B for the system of
		     linear equations.
		     On exit, the solution vectors, 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 = -k, the k-th argument had an illegal value
