DRZT02

Function/Subroutine Documentation

  double precision function drzt02 (integer m, integer n, double precision, dimension( lda, * ) af, integer lda, double precision, dimension( * ) tau, double precision, dimension( lwork ) work, integer lwork)

DRZT02

Purpose:

     DRZT02 returns
          || I - Q'*Q || / ( M * eps)
     where the matrix Q is defined by the Householder transformations
     generated by DTZRZF.

Parameters
    M

              M is INTEGER
              The number of rows of the matrix AF.

    N

              N is INTEGER
              The number of columns of the matrix AF.

    AF

              AF is DOUBLE PRECISION array, dimension (LDA,N)
              The output of DTZRZF.

    LDA

              LDA is INTEGER
              The leading dimension of the array AF.

    TAU

              TAU is DOUBLE PRECISION array, dimension (M)
              Details of the Householder transformations as returned by
              DTZRZF.

    WORK

              WORK is DOUBLE PRECISION array, dimension (LWORK)

    LWORK

              LWORK is INTEGER
              length of WORK array. LWORK >= N*N+N*NB.
