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 size M. 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) DOUBLE PRECISION The minimum time a subroutine will be timed. A (workspace) DOUBLE PRECISION array, dimension (NMAX*2) where NMAX is the maximum value permitted for N. B (workspace) DOUBLE PRECISION array, dimension (LDAMAX*NMAX) RESLTS (output) DOUBLE PRECISION array, dimension (LDR1,LDR2,LDR3,NSUBS) The timing results for each subroutine over the relevant values of N. LDR1 (input) INTEGER The first dimension of RESLTS. LDR1 >= 1. LDR2 (input) INTEGER The second dimension of RESLTS. LDR2 >= max(1,NM). LDR3 (input) INTEGER The third dimension of RESLTS. LDR3 >= max(1,NLDA). NOUT (input) INTEGER The unit number for output. ===================================================================== Parameter adjustments */ --mval; --nsval; --ldaval; --a; --b; reslts_dim1 = *ldr1; reslts_dim2 = *ldr2; reslts_dim3 = *ldr3; reslts_offset = 1 + reslts_dim1 * (1 + reslts_dim2 * (1 + reslts_dim3 * 1) ); reslts -= reslts_offset; /* Function Body Extract the timing request from the input line. */ s_copy(path, "Double precision", (ftnlen)1, (ftnlen)16); s_copy(path + 1, "PT", (ftnlen)2, (ftnlen)2); atimin_(path, line, &c__4, subnam, timsub, nout, &info, (ftnlen)3, ( ftnlen)80, (ftnlen)6); if (info != 0) { goto L170; } /* Check that N <= LDA for the input values. */ for (isub = 2; isub <= 4; ++isub) { if (!
