🌸 NAME 🌸

Okay so this is the Library Functions Manual page for /home/abui...ercond_x.f(3), and the file it's documenting is /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/cla_gercond_x.f. The main character? CLA_GERCOND_X, no cap: it computes the infinity norm condition number of op(A)*diag(x) for general matrices. 💅

✨ SYNOPSIS ✨

💫 Functions/Subroutines 💫

• real function CLA_GERCOND_X (trans, n, a, lda, af, ldaf, ipiv, x, info, work, rwork) — computes the infinity norm condition number of op(A)*diag(x) for general matrices.

🧚 Function/Subroutine Documentation 🧚

real function CLA_GERCOND_X (character trans, integer n, complex, dimension(
       lda, * ) a, integer lda, complex, dimension( ldaf, * ) af, integer ldaf,
       integer, dimension( * ) ipiv, complex, dimension( * ) x, integer info,
       complex, dimension( * ) work, real, dimension( * ) rwork)

This is the full signature, bestie — CLA_GERCOND_X computes the infinity norm condition number of op(A)*diag(x) for general matrices. Obsessed. 🫶

💖 Purpose 💖

CLA_GERCOND_X computes the infinity norm condition number of op(A) * diag(X) where X is a COMPLEX vector. That's the whole vibe. ✨

🌈 Parameters 🌈

• TRANS — TRANS is CHARACTER*1. Specifies the form of the system of equations:
  • = 'N': A * X = B (No transpose)
  • = 'T': A**T * X = B (Transpose)
  • = 'C': A**H * X = B (Conjugate Transpose = Transpose)
• N — N is INTEGER. The number of linear equations, i.e., the order of the matrix A. N >= 0.
• A — A is COMPLEX array, dimension (LDA,N). On entry, the N-by-N matrix A.
• LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,N).
• AF — AF is COMPLEX array, dimension (LDAF,N). The factors L and U from the factorization A = P*L*U as computed by CGETRF.
• LDAF — LDAF is INTEGER. The leading dimension of the array AF. LDAF >= max(1,N).
• IPIV — IPIV is INTEGER array, dimension (N). The pivot indices from the factorization A = P*L*U as computed by CGETRF; row i of the matrix was interchanged with row IPIV(i).
• X — X is COMPLEX array, dimension (N). The vector X in the formula op(A) * diag(X).
• INFO — INFO is INTEGER.
  • = 0: Successful exit.
  • i > 0: The ith argument is invalid.
• WORK — WORK is COMPLEX array, dimension (2*N). Workspace.
• RWORK — RWORK is REAL array, dimension (N). Workspace.
