💅 TESTING/LIN/dlatb5.f 💅

okay so this is the page for TESTING/LIN/dlatb5.f from the Library Functions Manual — yes, the whole thing is tagged TESTING/LIN/dlatb5.f(3). it’s giving very specific LAPACK test-matrix energy, and honestly? lowkey obsessed. the vibe check passed. slay. 🎀

✨ NAME ✨

TESTING/LIN/dlatb5.f

🦋 SYNOPSIS 🦋

Functions/Subroutines

       subroutine dlatb5 (path, imat, n, type, kl, ku, anorm, mode, cndnum,
           dist)
           DLATB5

🌸 Function/Subroutine Documentation 🌸

🧚 subroutine dlatb5

   subroutine dlatb5 (character*3 path, integer imat, integer n, character
       type, integer kl, integer ku, double precision anorm, integer mode,
       double precision cndnum, character dist)
       DLATB5

🎯 Purpose: 🎯

DLATB5 sets parameters for the matrix generator based on the type of matrix to be generated. that’s the whole assignment, bestie. fr fr. 💖

🔥 Parameters 🔥

  • PATH — PATH is CHARACTER*3. it’s the LAPACK path name. 👑
  • IMAT — IMAT is INTEGER. an integer key describing which matrix to generate for this path. iykyk.
  • N — N is INTEGER. the number of rows and columns in the matrix to be generated.
  • TYPE — TYPE is CHARACTER*1. literally 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. no cap.
  • 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. periodt.
