Okay bestie, quick vibe check: this page is from the Library Functions Manual, and that path up there is the file it's documenting. We're talking about ZLA_HERCOND_C, and it's giving main-character LAPACK energy. 🫶

✨ SYNOPSIS ✨

Functions/Subroutines

double precision function ZLA_HERCOND_C (uplo, n, a, lda, af, ldaf,
    ipiv, c, capply, info, work, rwork)

So the synopsis is right there, and the tea is: ZLA_HERCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for Hermitian indefinite matrices. Slay. 💅

🌸 Function/Subroutine Documentation 🌸

double precision function ZLA_HERCOND_C (character uplo, integer n,
    complex*16, dimension( lda, * ) a, integer lda, complex*16, dimension(
    ldaf, * ) af, integer ldaf, integer, dimension( * ) ipiv, double
    precision, dimension ( * ) c, logical capply, integer info, complex*16,
    dimension( * ) work, double precision, dimension( * ) rwork)

ZLA_HERCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for Hermitian indefinite matrices. That's the whole function vibe, periodt. ✨

🎀 Purpose 🎀

!>
!>    ZLA_HERCOND_C computes the infinity norm condition number of
!>    op(A) * inv(diag(C)) where C is a DOUBLE PRECISION vector.
!>

Translation for the group chat: it's computing the infinity norm condition number of op(A) * inv(diag(C)), and C is a DOUBLE PRECISION vector. No cap, that's the purpose. 💖

💅 Parameters 💅

• UPLO — CHARACTER*1. = 'U': upper triangle of A is stored; = 'L': lower triangle of A is stored.
• N — INTEGER. The number of linear equations, i.e., the order of the matrix A. N >= 0.
• A — COMPLEX*16 array, dimension (LDA,N). On entry, the N-by-N matrix A.
• LDA — INTEGER. The leading dimension of the array A. LDA >= max(1,N).
• AF — COMPLEX*16 array, dimension (LDAF,N). The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by ZHETRF.
• LDAF — INTEGER. The leading dimension of the array AF. LDAF >= max(1,N).
• IPIV — INTEGER array, dimension (N). Details of the interchanges and the block structure of D as determined by CHETRF.
• C — DOUBLE PRECISION array, dimension (N). The vector C in the formula op(A) * inv(diag(C)).
• CAPPLY — LOGICAL. If .TRUE. then access the vector C in the formula above.
• INFO — INTEGER. = 0: successful exit. i > 0: the ith argument is invalid.
• WORK — COMPLEX*16 array, dimension (2*N). Workspace.
• RWORK — DOUBLE PRECISION array, dimension (N). Workspace.

Okay that's the whole page, bestie! Cute sign-off time: LAPACK Version 3.12.0, with the footer's page source /home/abui...ercond_c.f(3). No date is shown in the footer, so I'm not inventing one — fr fr. 💖✨
