/* Purpose */
/* ======= */
/* CLAGTM performs a matrix-vector product of the form */
/* B := alpha * A * X + beta * B */
/* where A is a tridiagonal matrix of order N, B and X are N by NRHS */
/* matrices, and alpha and beta are real scalars, each of which may be */
/* 0., 1., or -1. */
/* Arguments */
/* ========= */
/* TRANS (input) CHARACTER*1 */
/* Specifies the operation applied to A. */
/* = 'N': No transpose, B := alpha * A * X + beta * B */
/* = 'T': Transpose, B := alpha * A**T * X + beta * B */
/* = 'C': Conjugate transpose, B := alpha * A**H * X + beta * B */
/* N (input) INTEGER */
/* The order of the matrix A. N >= 0. */
/* NRHS (input) INTEGER */
/* The number of right hand sides, i.e., the number of columns */
/* of the matrices X and B. */
/* ALPHA (input) REAL */
/* The scalar alpha. ALPHA must be 0., 1., or -1.; otherwise, */
/* it is assumed to be 0. */
/* DL (input) COMPLEX array, dimension (N-1) */
/* The (n-1) sub-diagonal elements of T. */
/* D (input) COMPLEX array, dimension (N) */
/* The diagonal elements of T. */
/* DU (input) COMPLEX array, dimension (N-1) */
/* The (n-1) super-diagonal elements of T. */
/* X (input) COMPLEX array, dimension (LDX,NRHS) */
/* The N by NRHS matrix X. */
/* LDX (input) INTEGER */
/* The leading dimension of the array X. LDX >= max(N,1). */
/* BETA (input) REAL */
/* The scalar beta. BETA must be 0., 1., or -1.; otherwise, */
/* it is assumed to be 1. */
/* B (input/output) COMPLEX 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 (input) INTEGER */
/* The leading dimension of the array B. LDB >= max(N,1). */
