PDL should be faster (after compilation)
#!/usr/bin/perl -- use strict; use warnings; use PDL; use Inline qw( Pdlpp ); print pdl(1)->eight,"\n"; print pdl(10)->eight,"\n"; print pdl(100)->eight,"\n"; print pdl(100000000 )->eight,"\n"; __DATA__ __Pdlpp__ pp_addhdr( ' double eight_sum(int n) { int i, sum = 0; for (i=1; i<=n; i++) { sum += i; } return sum; } ' ); pp_def( 'eight', Pars => 'int a(); int [o]b();', Code => '$b()=eight_sum($a());' ); pp_done();
On my system
time perl inline.pdlpp2.pl 1 55 5050 987459712 real 1.00 user 0.00 sys 0.00
