🌸 NAME 🌸

okay so bestie, this page lives in the Library Functions Manual, and its main-character title is TESTING/LIN/cqrt04.f. It's the doc for cqrt04, the test routine that checks CGEQRT and CGEMQRT. 💅

✨ SYNOPSIS ✨

Functions/Subroutines

  • subroutine cqrt04 (m, n, nb, result) — CQRT04
subroutine cqrt04 (m, n, nb, result)
    CQRT04

🦋 Function/Subroutine Documentation 🦋

subroutine cqrt04 (integer m, integer n, integer nb, real, dimension(6) result)

CQRT04

Purpose

CQRT04 tests CGEQRT and CGEMQRT. That's the whole purpose, no cap. 🔥

Parameters

  • M — M is INTEGER; it's the number of rows in the test matrix. 💖
  • N — N is INTEGER; it's the number of columns in the test matrix. 🌸
  • NB — NB is INTEGER; it's the block size of the test matrix, and NB <= Min(M,N). 🎀
  • RESULT — RESULT is REAL array, dimension (6); these are the results of each of the six tests below, and yes, all six are iconic:
    • 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 |
