    Purpose   
    =======   

    DTIMMV times individual BLAS 2 routines.   

    Arguments   
    =========   

    VNAME   (input) CHARACTER*(*)   
            The name of the Level 2 BLAS routine to be timed.   

    NN      (input) INTEGER   
            The number of values of N contained in the vector NVAL.   

    NVAL    (input) INTEGER array, dimension (NN)   
            The values of the matrix dimension N.   

    NK      (input) INTEGER   
            The number of values of K contained in the vector KVAL.   

    KVAL    (input) INTEGER array, dimension (NK)   
            The values of the bandwidth K.   

    NLDA    (input) INTEGER   
            The number of values of LDA contained in the vector LDAVAL.   

    LDAVAL  (input) INTEGER array, dimension (NLDA)   
            The values of the leading dimension of the array A.   

    TIMMIN  (input) DOUBLE PRECISION   
            The minimum time a subroutine will be timed.   

    A       (workspace) DOUBLE PRECISION array, dimension (LDAMAX*NMAX)   
               where LDAMAX and NMAX are the maximum values permitted   
               for LDA and N.   

    LB      (input) INTEGER   
            The length of B and C, needed when timing DGBMV.  If timing   
            DGEMV, LB >= LDAMAX*NMAX.   

    B       (workspace) DOUBLE PRECISION array, dimension (LB)   

    C       (workspace) DOUBLE PRECISION array, dimension (LB)   

    RESLTS  (output) DOUBLE PRECISION array, dimension (LDR1,LDR2,NLDA)   
            The timing results for each subroutine over the relevant   
            values of N and LDA.   

    LDR1    (input) INTEGER   
            The first dimension of RESLTS.  LDR1 >= max(1,NK).   

    LDR2    (input) INTEGER   
            The second dimension of RESLTS.  LDR2 >= max(1,NN).   

    NOUT    (input) INTEGER   
            The unit number for output.
