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