/home/abui...yrcond_c.f(3)

Okay bestie, welcome to the cla_syrcond_c.f(3) page from the Library Functions Manual — the header is being all mysterious with /home/abui...yrcond_c.f(3), but the actual source file is fully named down in NAME. This is a LAPACK situation, and it's giving “I know linear algebra and I'm not sorry” energy. 💅✨

🎀 NAME 🎀

The source file for this function is:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/cla_syrcond_c.f

No cap, that's the whole path. 🫶

✨ SYNOPSIS ✨

Functions/Subroutines

real function CLA_SYRCOND_C (uplo, n, a, lda, af, ldaf, ipiv, c, capply,
    info, work, rwork)

CLA_SYRCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for symmetric indefinite matrices. Slay. 💖

🌈 real function CLA_SYRCOND_C 🌈

real function CLA_SYRCOND_C (character uplo, integer n, complex, dimension(
    lda, * ) a, integer lda, complex, dimension( ldaf, * ) af, integer ldaf,
    integer, dimension( * ) ipiv, real, dimension( * ) c, logical capply,
    integer info, complex, dimension( * ) work, real, dimension( * ) rwork)

CLA_SYRCOND_C computes the infinity norm condition number of op(A)*inv(diag(c)) for symmetric indefinite matrices. That's the whole function vibe check. ✅

💡 Purpose

Okay so the actual purpose: CLA_SYRCOND_C computes the infinity norm condition number of op(A) * inv(diag(C)) where C is a REAL vector. That's it, that's the math. 🧮✨

🧾 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 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 array, dimension (LDAF,N). The block diagonal matrix D and the multipliers used to obtain the factor U or L as computed by CSYTRF.
• 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 CSYTRF.
• C — REAL 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 array, dimension (2*N). Workspace.
• RWORK — REAL array, dimension (N). Workspace.
