CLATB5

Purpose:

    !>
    !> CLATB5 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 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.
    !>
