💅 TESTING/LIN/dlatb4.f — Library Functions Manual ✨

🌸 NAME 🌸

TESTING/LIN/dlatb4.f — that's literally the whole name section, bestie. Minimal, iconic, no notes. 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine dlatb4 (path, imat, m, n, type, kl, ku, anorm, mode, cndnum, dist)
    DLATB4

💖 Function/Subroutine Documentation 💖

Okay so here's the full signature, every type and argument laid out, no cap:

   subroutine dlatb4 (character*3 path, integer imat, integer m, integer n,
       character type, integer kl, integer ku, double precision anorm, integer
       mode, double precision cndnum, character dist)
       DLATB4

🎀 Purpose 🎀

DLATB4 sets parameters for the matrix generator based on the type of matrix to be generated. In the source it's wrapped in !> doxygen comment lines — very demure, very mindful. 🫶

🦋 Parameters 🦋

  • PATH — PATH is CHARACTER*3. It's the LAPACK path name, bestie. 🛣️
  • IMAT — IMAT is INTEGER. An integer key describing which matrix to generate for this path. 🔑
  • M — M is INTEGER. The number of rows in the matrix to be generated. 📏
  • N — N is INTEGER. The number of columns in the matrix to be generated. 📐
  • TYPE — TYPE is CHARACTER*1. The type of the matrix to be generated:
    • = 'S': symmetric matrix
    • = 'P': symmetric positive (semi)definite matrix
    • = 'N': nonsymmetric matrix
  • KL — KL is INTEGER. The lower band width of the matrix to be generated. 🌊
  • KU — KU is INTEGER. The upper band width of the matrix to be generated. 🌊
  • ANORM — ANORM is DOUBLE PRECISION. 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. A key indicating how to choose the vector of eigenvalues. 🎛️
  • CNDNUM — CNDNUM is DOUBLE PRECISION. The desired condition number. 🔢
  • DIST — DIST is CHARACTER*1. The type of distribution to be used by the random number generator. 🎲
