    Purpose   
    =======   

    CTIMTB times CTBTRS.   

    Arguments   
    =========   

    LINE    (input) CHARACTER*80   
            The input line that requested this routine.  The first six   
            characters contain either the name of a subroutine or a   
            generic path name.  The remaining characters may be used to   
            specify the individual routines to be timed.  See ATIMIN for   
            a full description of the format of the input line.   

    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 size 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 band width K.   

    NNS     (input) INTEGER   
            The number of values of NRHS contained in the vector NSVAL.   

    NSVAL   (input) INTEGER array, dimension (NNS)   
            The values of the number of right hand sides NRHS.   

    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) REAL   
            The minimum time a subroutine will be timed.   

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

    B       (workspace) COMPLEX array, dimension (LDAMAX*NMAX)   

    RESLTS  (output) REAL array, dimension   
                     (LDR1,LDR2,LDR3,NSUBS)   
            The timing results for each subroutine over the relevant   
            values of N, NB, and LDA.   

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

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

    LDR3    (input) INTEGER   
            The third dimension of RESLTS.  LDR3 >= max(1,2*NLDA).   

    NOUT    (input) INTEGER   
            The unit number for output.
