🎀 Purpose 🎀

The purpose block is literally: SQRT05 tests STPLQT and STPMLQT. (Yes, it says SQRT05 there — we're not editing the lore, bestie.) ✨

✨ Parameters ✨

  • 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 REAL array, dimension (6). Results of each of the six tests below.

The six tests are giving exact formula realness:

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 |
