Intersection(A,B) not working for date

I have A and B date vectors. I want to extract the common dates from both. I used:

[C,ia, ib]=intersection(A,B)

But it is giving me extremely few results than expected. Any solution?

Answer 1

you should use a round before using using intersection to avoid floats not being equal to each other. If the dates are distinguishably by day (i.e. no hours given) you could use this

[C,ia, ib]=intersection(round(A),round(B))

This answer would be more or less correct if the OP was using date numbers. But for accuracy down to the second, I would actually multiply the date numbers by 24x3600 before rounding.

As the OP is using date vectors though, Star's answer is the correct one.

Since date vectors are row vectors, use the 'rows' option with intersect:

[C,ia, ib]=intersect(A,B,'rows');
