ZQRT05 — iconic name, honestly.

💫 Purpose 💫

In the source, the purpose is wrapped in Doxygen !> comment markers; the actual line is ZQRT05 tests ZTPQRT and ZTPMQRT. Same !> marker situation for every parameter blurb below, iykyk.

• M — M is INTEGER. Number of rows in lower part of the test matrix.
• N — N is INTEGER. Number of columns in test matrix.
• L — L is INTEGER. The number of rows of the upper trapezoidal part the lower test matrix. 0 <= L <= M.
• NB — NB is INTEGER. Block size of test matrix. NB <= N.
• 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 |
