SYNOPSIS

double precision function drzt02 (m, n, af, lda, tau, work, lwork)
DRZT02

DRZT02

Purpose:



 DRZT02 returns


      || I - Q'*Q || / ( M * eps)


 where the matrix Q is defined by the Householder transformations


 generated by DTZRZF.

Parameters



          M is INTEGER


          The number of rows of the matrix AF.



          N is INTEGER


          The number of columns of the matrix 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.
