/*  -- LAPACK timing routine (version 3.0) --   
       Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,   
       Courant Institute, Argonne National Lab, and Rice University   
       February 29, 1992   


    Purpose   
    =======   

    DOPLA2 computes an approximation of the number of floating point   
    operations used by the subroutine SUBNAM with character options   
    OPTS and parameters M, N, K, L, and NB.   

    This version counts operations for the LAPACK subroutines that   
    call other LAPACK routines.   

    Arguments   
    =========   

    SUBNAM  (input) CHARACTER*6   
            The name of the subroutine.   

    OPTS    (input) CHRACTER*(*)   
            A string of character options to subroutine SUBNAM.   

    M       (input) INTEGER   
            The number of rows of the coefficient matrix.   

    N       (input) INTEGER   
            The number of columns of the coefficient matrix.   

    K       (input) INTEGER   
            A third problem dimension, if needed.   

    L       (input) INTEGER   
            A fourth problem dimension, if needed.   

    NB      (input) INTEGER   
            The block size.  If needed, NB >= 1.   

    Notes   
    =====   

    In the comments below, the association is given between arguments   
    in the requested subroutine and local arguments.  For example,   

    xORMBR:  VECT // SIDE // TRANS, M, N, K   =>  OPTS, M, N, K   

    means that the character string VECT // SIDE // TRANS is passed to   
    the argument OPTS, and the integer parameters M, N, and K are passed   
    to the arguments M, N, and K,
