Origin Ver. and Service Release (Select Help-->About Origin):7.5SR6
Operating System:winXP

Hi!

Is there a faster method than the simple yDataset(interpolatedXValue) for Origin 7.5? It is rather slow when I used the simple method to interpolate my data (100k points, several columns).

Thank you in advance!

You should consider upgrading. Origin 9.1 is about 15 times faster than Origin 7.5 under those circumstances as demonstrated by this script:

wo -a 2;
col(1) = 100+250*uniform(100000);
col(1) = sort(col(1));
col(2) = gauss(col(1),0,222,40,1200);
col(3) = data(100,350,.001);
sec;
col(4) = col(2)(col(3));
watch;

which outputs around 1 second for 9.1 and around 16 seconds for 7.5.
