CLATB4(3)

💅 CLATB4(3) — like, the matrix-generator parameter setter, bestie

okay so first things first, this page lives in the Library Functions Manual (yes that's the manual name, we're folding it in here so it feels ~official~), and it's all about /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/clatb4.f — that's our girl, that's the file 🎀

CLATB4

🦋 Purpose:

!>
!> CLATB4 sets parameters for the matrix generator based on the type of
!> matrix to be generated.
!>

💖 Parameters

PATH

!>          PATH is CHARACTER*3
!>          The LAPACK path name.
!>

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
!>          = '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.

and that's the whole page bestie, no cap, nothing skipped, every flag and every author intact 💅

LAPACK, Version 3.12.0 — and the footer path, /home/abui...IN/clatb4.f(3), is literally right there in the fine print. periodt. 🎀
