SYNOPSIS

double precision function zrzt02 (m, n, af, lda, tau, work, lwork)
ZRZT02

ZRZT02

Purpose:



 ZRZT02 returns


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


 where the matrix Q is defined by the Householder transformations


 generated by ZTZRZF.

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 COMPLEX*16 array, dimension (LDA,N)


          The output of ZTZRZF.

LDA



          LDA is INTEGER


          The leading dimension of the array AF.

TAU



          TAU is COMPLEX*16 array, dimension (M)


          Details of the Householder transformations as returned by


          ZTZRZF.

WORK



          WORK is COMPLEX*16 array, dimension (LWORK)

LWORK



          LWORK is INTEGER


          Length of WORK array. LWORK >= N*N+N.
