ZRZT02

Purpose:

 ZRZT02 returns
      || I - Q'*Q || / ( M * eps)
 where the matrix Q is defined by the Householder transformations
 generated by ZTZRZF.
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 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.
