Thread Subject: intersect point

Subject: intersect point

Hello,
I have two vectors and I'm looking for the intersect points. Plotting the
vectors they cross each other several times. But it wouldn't work with
find(v1 = = v2) because the intersect point is between to points in the
vectors.
How can I find the real intersect points.

Thanks a lot.
Andrea

You will find at least two solutions by looking on
the file exchange, with the keyword "intersections".

HTH,

Try to use ismember(A, B, 'rows')

This will not work for your problem; refer to the first
reply.
