       Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..   
       November 2006   


    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).
