ZQRT05
ZQRT05 tests ZTPQRT and ZTPMQRT.
[in] | M | M is INTEGER Number of rows in lower part of the test matrix. |
[in] | N | N is INTEGER Number of columns in test matrix. |
[in] | L | L is INTEGER The number of rows of the upper trapezoidal part the lower test matrix. 0 <= L <= M. |
[in] | NB | NB is INTEGER Block size of test matrix. NB <= N. |
[out] | RESULT | RESULT is DOUBLE PRECISION array, dimension (6) Results of each of the six tests below. RESULT(1) = | A - Q R | RESULT(2) = | I - Q^H Q | RESULT(3) = | Q C - Q C | RESULT(4) = | Q^H C - Q^H C | RESULT(5) = | C Q - C Q | RESULT(6) = | C Q^H - C Q^H | |
