SQRT04(3)

🎀 SQRT04(3) — Library Functions Manual 🎀

okay bestie, this is the sqrt04.f(3) page from the Library Functions Manual — header path folded in like a good little intro: /home/abui...IN/sqrt04.f(3). Let’s get into it. 💅✨

📛 NAME 📛

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/sqrt04.f

🌈 SYNOPSIS 🌈

Functions/Subroutines 🦋

• subroutine SQRT04 (m, n, nb, result) — SQRT04

🌸 Function/Subroutine Documentation 🌸

🫶 the typed signature 🫶

   subroutine SQRT04 (integer m, integer n, integer nb, real, dimension(6)
       result)

SQRT04

✨ Purpose ✨

!>
!> SQRT04 tests SGEQRT and SGEMQRT.
!>

🎀 Parameters 🎀

M — row-count energy. Exact spec:

!>          M is INTEGER
!>          Number of rows in test matrix.
!>

N — column-count energy. Exact spec:

!>          N is INTEGER
!>          Number of columns in test matrix.
!>

NB — block-size energy, and yes: NB <= Min(M,N). Exact spec:

!>          NB is INTEGER
!>          Block size of test matrix.  NB <= Min(M,N).
!>

RESULT — a REAL array, dimension (6), holding the results of each of the six tests below. Exact spec:

!>          RESULT is REAL 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 |
