Class DLAGTM

    java.lang.Object
      org.netlib.lapack.DLAGTM

    public class DLAGTM

extends java.lang.Object

    DLAGTM is a simplified interface to the JLAPACK routine dlagtm.
    This interface converts Java-style 2D row-major arrays into
    the 1D column-major linearized arrays expected by the lower
    level JLAPACK routines.  Using this interface also allows you
    to omit offset and leading dimension arguments.  However, because
    of these conversions, these routines will be slower than the low
    level ones.  Following is the description from the original Fortran
    source.  Contact seymour@cs.utk.edu with any questions.

     *     ..
     *
     *  Purpose
     *  =======
     *
     *  DLAGTM 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'* X + beta * B
     *          = 'C':  Conjugate transpose = Transpose
     *
     *  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) DOUBLE PRECISION
     *          The scalar alpha.  ALPHA must be 0., 1., or -1.; otherwise,
     *          it is assumed to be 0.
     *
     *  DL      (input) DOUBLE PRECISION array, dimension (N-1)
     *          The (n-1) sub-diagonal elements of T.
     *
     *  D       (input) DOUBLE PRECISION array, dimension (N)
     *          The diagonal elements of T.
     *
     *  DU      (input) DOUBLE PRECISION array, dimension (N-1)
     *          The (n-1) super-diagonal elements of T.
     *
     *  X       (input) DOUBLE PRECISION 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) DOUBLE PRECISION
     *          The scalar beta.  BETA must be 0., 1., or -1.; otherwise,
     *          it is assumed to be 1.
     *
     *  B       (input/output) DOUBLE PRECISION 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).
