CRZT02
Purpose:
!> !> CRZT02 returns !> || I - Q'*Q || / ( M * eps) !> where the matrix Q is defined by the Householder transformations !> generated by CTZRZF. !>
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 array, dimension (LDA,N) !> The output of CTZRZF. !>
LDA
!> LDA is INTEGER !> The leading dimension of the array AF. !>
TAU
!> TAU is COMPLEX array, dimension (M) !> Details of the Householder transformations as returned by !> CTZRZF. !>
WORK
!> WORK is COMPLEX array, dimension (LWORK) !>
LWORK
!> LWORK is INTEGER !> Length of WORK array. LWORK >= N*N+N. !>
