Hello everyone,
I am looking for a way to couple the 'rows' option with a set tolerance. I have a array of points A whose coordinates form a ring. Once I rotate them by a given angle I obtain a set of points B whose coordinates should match the ones of A. My goal is to find the row j of array B which equals the row i of array A. Given that the rotation creates some numerical error I won't have perfect match, that's why I'm looking for a way which could overcome this issue.

You can calculate the pairwise distance and set a threshold to accept two vectors as equal.

Thank you Jan. I also thought to use sortrows function as it is used within ismember. Still the issue is to properly rank the vector taking a set tolerance into account. Due to the big size of my array, would you recommend to use some sort of arrayfun to calculate the pairwise distance?
