* -- LAPACK timing routine (version 3.0) --
* Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
* Courant Institute, Argonne National Lab, and Rice University
* March 31, 1993
*
* .. Scalar Arguments ..
CHARACTER*( * ) LINE
INTEGER LA, LDR1, LDR2, NINC, NK, NLDA, NM, NN, NOUT
DOUBLE PRECISION TIMMIN
* ..
* .. Array Arguments ..
INTEGER INCVAL( * ), KVAL( * ), LDAVAL( * ), MVAL( * ),
$ NVAL( * )
DOUBLE PRECISION A( * ), RESLTS( LDR1, LDR2, * ), X( * ), Y( * )
* ..
*
* Purpose
* =======
*
* DTIMB2 times the BLAS 2 routines.
*
* 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.
*
* NM (input) INTEGER
* The number of values of M contained in the vector MVAL.
*
* MVAL (input) INTEGER array, dimension (NM)
* The values of the matrix row dimension M.
*
* 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 column 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 band width K.
*
* NINC (input) INTEGER
* The number of values of INCX contained in the vector INCVAL.
*
* INCVAL (input) INTEGER array, dimension (NINC)
* The values of INCX, the increment between successive values
* of the vector X.
*
* 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.
*
* LA (input) INTEGER
* The size of the array A.
*
* TIMMIN (input) DOUBLE PRECISION
* The minimum time a subroutine will be timed.
*
* A (workspace) DOUBLE PRECISION array, dimension (LA)
*
* X (workspace) DOUBLE PRECISION array, dimension (NMAX*INCMAX)
* where NMAX and INCMAX are the maximum values permitted
* for N and INCX.
*
* Y (workspace) DOUBLE PRECISION array, dimension (NMAX*INCMAX)
* where NMAX and INCMAX are the maximum values permitted
* for N and INCX.
*
* RESLTS (output) DOUBLE PRECISION array, dimension (LDR1,LDR2,p),
* where p = NLDA*NINC.
* The timing results for each subroutine over the relevant
* values of M, N, K, INCX, and LDA.
*
* LDR1 (input) INTEGER
* The first dimension of RESLTS. LDR1 >= max(1,NM,NK).
*
* LDR2 (input) INTEGER
* The second dimension of RESLTS. LDR2 >= max(1,NN).
*
* NOUT (input) INTEGER
* The unit number for output.
*
