DLATB9

Purpose:



 DLATB9 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.


          = 1:   A: diagonal, B: upper triangular


          = 2:   A: upper triangular, B: upper triangular


          = 3:   A: lower triangular, B: upper triangular


          Else:  A: general dense, B: general dense



          M is INTEGER


          The number of rows in the matrix to be generated.



          P is INTEGER



          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.

KLA



          KLA is INTEGER


          The lower band width of the matrix to be generated.

KUA



          KUA is INTEGER


          The upper band width of the matrix to be generated.

KLB



          KLB is INTEGER


          The lower band width of the matrix to be generated.

KUB



          KUA 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.

BNORM



          BNORM 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.

MODEA



          MODEA is INTEGER


          A key indicating how to choose the vector of eigenvalues.

MODEB



          MODEB is INTEGER


          A key indicating how to choose the vector of eigenvalues.

CNDNMA



          CNDNMA is DOUBLE PRECISION


          The desired condition number.

CNDNMB



          CNDNMB is DOUBLE PRECISION


          The desired condition number.

DISTA



          DISTA is CHARACTER*1


          The type of distribution to be used by the random number


          generator.

DISTB



          DISTB is CHARACTER*1


          The type of distribution to be used by the random number


          generator.
