How comparing vectors defined in different ranges?

2 views (last 30 days)
Hi! I'm writing a script to extract a laser profile from an image and make some measures. I have two different vectors: first one with my model and a second one with the laser relief.
The two vectors have different lenghts and their x-values are different, but defined in the same range [0,200] (measures are in mm).
There is a way to compare the two vectors and compute the offset error from each others, or there is a better way to do that? Functions as intersect and ismember doesn't work for me, because x-values are double and the two vectors have null intersection.
Thanks

If your data are relatively smooth, consider using the interp1 function to interpolate to get common y values for both at the same defined x values.
