## Function/Subroutine Documentation

### real function crzt02 (integer m, integer n, complex, dimension( lda, * ) af, integer lda, complex, dimension( * ) tau, complex, dimension( lwork ) work, integer lwork)

**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.
