💖 ZLAIPD(3) — Library Functions Manual 💖

okay bestie, welcome to ZLAIPD(3) from the Library Functions Manual — this one is a little LAPACK test-helper icon and I’m obsessed 💅✨

🌸 NAME 🌸

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

that’s literally the file path, no cap 🫶

🦋 SYNOPSIS 🦋

Functions/Subroutines

subroutine ZLAIPD (n, a, inda, vinda)
    ZLAIPD

so yes, the subroutine is ZLAIPD (n, a, inda, vinda) and it’s giving exactly that ✨

🎀 Function/Subroutine Documentation 🎀

subroutine ZLAIPD (integer n, complex*16, dimension( * ) a, integer inda,
    integer vinda)
    ZLAIPD

💜 Purpose 💜

ZLAIPD sets the imaginary part of the diagonal elements of a complex matrix A to a large value. This is used to test LAPACK routines for complex Hermitian matrices, which are not supposed to access or use the imaginary parts of the diagonals. like, the whole vibe check is catching any routine that peeks where it shouldn’t 👀🔥

🍓 Parameters 🍓

• N — N is INTEGER; the number of diagonal elements of A.
• A — A is COMPLEX*16 array, dimension (1+(N-1)*INDA+(N-2)*VINDA). On entry, the complex (Hermitian) matrix A. On exit, the imaginary parts of the diagonal elements are set to BIGNUM = EPS / SAFMIN, where EPS is the machine epsilon and SAFMIN is the safe minimum. periodt 💅
• INDA — INDA is INTEGER; the increment between A(1) and the next diagonal element of A. Typical values are:
  • = LDA+1: square matrices with leading dimension LDA
  • = 2: packed upper triangular matrix, starting at A(1,1)
  • = N: packed lower triangular matrix, starting at A(1,1)
• VINDA — VINDA is INTEGER; the change in the diagonal increment between columns of A. Typical values are:
  • = 0: no change, the row and column increments in A are fixed
  • = 1: packed upper triangular matrix
  • = -1: packed lower triangular matrix
