Intersection simply use intersect with the stable option Union to keep the order of the two vectors (like they were zipped or interleaved together), then you could concatenate the vectors and then use unique like this If the vectors have different lengths then you could use this FEX submission to zip them together (instead. P0 end point 1 of the segment P0P1. f (t) a vat. are vectors returns the values common to all A,B,C. Find intersection of two lines. 7; 0. In set theoretic terms, this is a b. This is my method for determining if a polygon is intersecting. The resulting vector is sorted in ascending order. The polygon has no isolated points or edges, nor does it have dangling edges.
