hey bestie, you're reading TESTING/LIN/clatb4.f(3) from the Library Functions Manual 💅✨

💖 NAME

TESTING/LIN/clatb4.f — the page for CLATB4, the little icon that sets parameters for the matrix generator based on the type of matrix being generated. 🫶

✨ SYNOPSIS

🧚 Functions/Subroutines

subroutine clatb4 (path, imat, m, n, type, kl, ku, anorm, mode, cndnum,
    dist)

👑 CLATB4

subroutine clatb4 (character*3 path, integer imat, integer m, integer n,
    character type, integer kl, integer ku, real anorm, integer mode, real cndnum,
    character dist)

CLATB4

🌸 Purpose:

okay so CLATB4 sets the parameters for the matrix generator based on what kind of matrix is going to be generated. literally its whole job, and it ate. 💖

🎀 Parameters

  • PATH — PATH is CHARACTER*3; it's the LAPACK path name. slay.
  • IMAT — IMAT is INTEGER; it's 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
    • = 'H': Hermitian matrix
    • = 'P': Hermitian 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 REAL; 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 REAL; the desired condition number.
  • DIST — DIST is CHARACTER*1; the type of distribution to be used by the random number generator.
