DLATB5

Purpose:

 DLATB5 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.

N

          N is INTEGER
          The number of rows and 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.
