SRZT01
SRZT01 returns || A - R*Q || / ( M * eps * ||A|| ) for an upper trapezoidal A that was factored with STZRZF.
[in] | M | M is INTEGER The number of rows of the matrices A and AF. |
[in] | N | N is INTEGER The number of columns of the matrices A and AF. |
[in] | A | A is REAL array, dimension (LDA,N) The original upper trapezoidal M by N matrix A. |
[in] | AF | AF is REAL array, dimension (LDA,N) The output of STZRZF for input matrix A. The lower triangle is not referenced. |
[in] | LDA | LDA is INTEGER The leading dimension of the arrays A and AF. |
[in] | TAU | TAU is REAL array, dimension (M) Details of the Householder transformations as returned by STZRZF. |
[out] | WORK | WORK is REAL array, dimension (LWORK) |
[in] | LWORK | LWORK is INTEGER The length of the array WORK. LWORK >= m*n + m*nb. |
