SLATB4

Purpose:

!>
!> SLATB4 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
!>          = '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 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.
!>
