Grid of points within a polygon by Sulimon Sattari

This function generates an array of points that lie within a given polygon (polygon, points, point)

polygrid( xv, yv, ppa)

inpolyhedron - are points inside a volume? by Sven

It's inpolygon(), but for 3D triangulated surfaces. (non-convex surfaces, too!) (inpolygon, inside, mesh)

inpolyhedron(varargin)

Points On Line by Ankur Pawar

Linearly spaced points between two point and ,point in Convex Hull test. (points on line, line, 2d)

[inHullPoints,inPointsIndex]=inConvHull(vert,face,testPoint...

points=pointsOnLine(point1,point2,numPoints)
