Function/Subroutine Documentation¶
subroutine ZLATB4 (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)¶
ZLATB4
Purpose:
!> !> ZLATB4 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 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. !>
