mpq_poly

Polygon moments

m = mpq_poly(v, p, q) is the PQ'th moment of the polygon with vertices described by the columns of v.

Notes

• The points must be sorted such that they follow the perimeter in sequence (counter-clockwise).
• If the points are clockwise the moments will all be negated, so centroids will be still be correct.
• If the first and last point in the list are the same, they are considered to be a single vertex.
