2D Line Curvature and Normals 1.0

LineCurvature2D, This function calculates the curvature of a 2D line. It first fits polygons to the points. Then calculates the analytical curvature from the polygons. K = LineCurvature2D(Vertices,Lines) inputs, Vertices : A M x 2 list of line points. (optional) Lines : A N x 2 list of line pieces, by indices of the vertices (if not set assume Lines=[1 2; 3 4 ; ... ; M-1 M]) outputs, K : M x 1 Curvature values..LineNormals2D, This function calculates the normals, of the line. Using the neighbouring points of each line/contour point, and forward an backward differences on the end points N=LineNormals2D(V,L) inputs, V : List of points/vertices 2 x M (optional) Lines : A N x 2 list of line pieces, by indices of the vertices (if not set assume Lines=[1 2; 3 4 ; ... ; M-1 M]) outputs, N : The normals of the Vertices 2 x M
