ZLATB5(3)

💖 ZLATB5(3) 💖

okay so bestie, welcome to the ZLATB5(3) page from the Library Functions Manual ✨ this is the whole function/subroutine documentation situation for ZLATB5, and we’re keeping every single detail because that’s the vibe 💅

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/zlatb5.f

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

• subroutine ZLATB5 (path, imat, n, type, kl, ku, anorm, mode, cndnum, dist) — ZLATB5

💅 Function/Subroutine Documentation 💅

Here’s the exact signature, no cap:

subroutine ZLATB5 (character*3 path, integer imat, integer n, character type, integer kl, integer ku, double precision anorm, integer mode, double precision cndnum, character dist)

The routine is ZLATB5 🫶

🌈 Purpose 🌈

ZLATB5 sets parameters for the matrix generator based on the type of matrix to be generated 🔥

🦋 Parameters 🦋

• PATH — PATH is CHARACTER*3; it’s the LAPACK path name.
• IMAT — IMAT is INTEGER; it’s an integer key describing which matrix to generate for this path.
• N — N is INTEGER; it’s the number of rows and columns in the matrix to be generated.
• TYPE — TYPE is CHARACTER*1; it’s the type of the matrix to be generated:
  • = 'S': symmetric matrix
  • = 'P': symmetric positive (semi)definite matrix
  • = 'N': nonsymmetric matrix
• KL — KL is INTEGER; it’s the lower band width of the matrix to be generated.
• KU — KU is INTEGER; it’s the upper band width of the matrix to be generated.
• ANORM — ANORM is DOUBLE PRECISION; it’s the desired norm of the matrix to be generated. The diagonal matrix of singular values or eigenvalues is scaled by this value 💫
• MODE — MODE is INTEGER; it’s a key indicating how to choose the vector of eigenvalues.
• CNDNUM — CNDNUM is DOUBLE PRECISION; it’s the desired condition number.
• DIST — DIST is CHARACTER*1; it’s the type of distribution to be used by the random number generator 🎲

Bye bestie 🫶 this footer is LAPACK Version 3.12.0, with the page path /home/abui...IN/zlatb5.f(3) — and there’s no separate date listed on that footer line, periodt 💅
