SYNOPSIS
   Functions/Subroutines
       subroutine dlatb4 (path, imat, m, n, type, kl, ku, anorm, mode, cndnum,
           dist)
           DLATB4

Function/Subroutine Documentation
   subroutine dlatb4 (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)
       DLATB4

       Purpose:


            DLATB4 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 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.
