Resample produces unexpected vector length

I have two vectors of simultaneously recorded physiological signals, one is sampled at 20 kHz and the other at 1 kHz. I'd like to sample the latter upwards so they can be analysed together.

Length of the 20 kHz vector = 1228446

Length of the 1 kHz vector = 61423

1228446 / 61423 = 20

Makes sense to me! But the command

resample(1kHzSignal,20,1);

Returns a vector with length = 1228460, not 1228446. What am I missing? It's late here, so pointing out the obvious is appreciated.

I think the error is in your arithmetic (?)

1228446 / 61423

ans = 19.9998

1228460 / 61423

ans = 20

Thanks, I just realised I had

turned on. Obvious is pointed out!
