CGET10(3)

πŸ“¦ version 3.12.0, in opensuse-leap 16.0

Welcome to the CGET10(3) page from the Library Functions Manual, bestie! πŸ’–βœ¨ This one is a Fortran subroutine moment, and we’re keeping every single detail while making it make sense. Slay. πŸ’…

🌸 NAME 🌸

The NAME section is lowkey just the source path, and it’s giving β€œdeep in the LAPACK build tree” energy: 🫢

✨ SYNOPSIS ✨

πŸŽ€ Functions/Subroutines πŸŽ€

Okay so the synopsis is short and sweet: the subroutine is CGET10, and the line right after it is literally just its own name again. Iconic behavior, honestly. πŸ’…

  • subroutine CGET10 (m, n, a, lda, b, ldb, work, rwork, result) β€” CGET10

πŸ¦‹ Function/Subroutine Documentation πŸ¦‹

Here’s the full signature, exactly as it appears, because Fortran commas and dimensions are not the place to freestyle: πŸ”₯

subroutine CGET10 (integer m, integer n, complex, dimension( lda, * ) a,
       integer lda, complex, dimension( ldb, * ) b, integer ldb, complex,
       dimension( * ) work, real, dimension( * ) rwork, real result)

CGET10

πŸ’œ Purpose πŸ’œ

The Purpose block is giving comparison-and-ratio main character energy. Here it is with the !> Doxygen markers exactly as the source shows: ⭐

           !>
           !> CGET10 compares two matrices A and B and computes the ratio
           !> RESULT = norm( A - B ) / ( norm(A) * M * EPS )
           !>

πŸ”₯ Parameters πŸ”₯

Vibe check on every parameter, no cap: πŸ’œ

  • M β€” M is INTEGER. The number of rows of the matrices A and B.
  • N β€” N is INTEGER. The number of columns of the matrices A and B.
  • A β€” A is COMPLEX array, dimension (LDA,N). The m by n matrix A.
  • LDA β€” LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,M).
  • B β€” B is COMPLEX array, dimension (LDB,N). The m by n matrix B.
  • LDB β€” LDB is INTEGER. The leading dimension of the array B. LDB >= max(1,M).
  • WORK β€” WORK is COMPLEX array, dimension (M).
  • RWORK β€” RWORK is COMPLEX array, dimension (M). Yes, it says COMPLEX right there in the source, bestie β€” not me changing it. πŸ™ˆ
  • RESULT β€” RESULT is REAL. RESULT = norm( A - B ) / ( norm(A) * M * EPS ).
