SYNOPSIS

       subroutine zlaptm (uplo, n, nrhs, alpha, d, e, x, ldx, beta, b, ldb)
           ZLAPTM

Function/Subroutine Documentation
   subroutine zlaptm (character uplo, integer n, integer nrhs, double
       precision alpha, double precision, dimension( * ) d, complex*16,
       dimension( * ) e, complex*16, dimension( ldx, * ) x, integer ldx,
       double precision beta, complex*16, dimension( ldb, * ) b, integer ldb)
       ZLAPTM

       Purpose:


            ZLAPTM multiplies an N by NRHS matrix X by a Hermitian tridiagonal
            matrix A and stores the result in a matrix B.  The operation has the
            form

               B := alpha * A * X + beta * B

            where alpha may be either 1. or -1. and beta may be 0., 1., or -1.

       Parameters
           UPLO

                     UPLO is CHARACTER
                     Specifies whether the superdiagonal or the subdiagonal of the
                     tridiagonal matrix A is stored.
                     = 'U':  Upper, E is the superdiagonal of A.
                     = 'L':  Lower, E is the subdiagonal of A.

           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 matrices X and B.

           ALPHA

                     ALPHA is DOUBLE PRECISION
                     The scalar alpha.  ALPHA must be 1. or -1.; otherwise,
                     it is assumed to be 0.

           D

                     D is DOUBLE PRECISION array, dimension (N)
                     The n diagonal elements of the tridiagonal matrix A.

           E

                     E is COMPLEX*16 array, dimension (N-1)
                     The (n-1) subdiagonal or superdiagonal elements of A.

           X

                     X is COMPLEX*16 array, dimension (LDX,NRHS)
                     The N by NRHS matrix X.

           LDX

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

           BETA

                     BETA is DOUBLE PRECISION
                     The scalar beta.  BETA must be 0., 1., or -1.; otherwise,
                     it is assumed to be 1.

           B

                     B is COMPLEX*16 array, dimension (LDB,NRHS)
                     On entry, the N by NRHS matrix B.
                     On exit, B is overwritten by the matrix expression
                     B := alpha * A * X + beta * B.

           LDB

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