Calculates triangles' centroids, areas, and heights from vertices

Usage

init_tris_cpp(triplets, pts)

Arguments

triplets

A M-by-3 matrix with indices for the points that correspond each triangle's vertices, where M is the number of triangles.

pts

A N-by-2 matrix with indices for the X,Y coordinates of each point.

Value

A M-by-4 matrix containing the X,Y coordinates of each triangle's centroid in the first two columns, and area and largest height of each triangle in the last two columns.
