Intersection

This script implements two methods to return the intersection/union of sets of data, where the form of the data is not a limiting factor. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This function returns the basis of the intersection of N subspaces defined by their bases, and the dimension of this intersection. The input basis vectors must be row vectors!Example:A = [1,1,-1,1; % Platforms: Matlab

OUT = LINESEGMENTINTERSECT(XY1,XY2) generates intersection analysis between the line segment sets given in XY1 and XY2. Code can handle coincident and parallel lines.The main emphasis is on speed. The code is fully vectorized and it runs pretty fast (orders of magnitude) compared to some of the... Platforms: Matlab

An add-on for AUTOCAD 2002-2018 or BricsCAD V15-V17, which determines the intersection curves between 2 sets consisting of 3DFACE, 3DSOLID or 3DMESH entities. The outcome is represented by 3DPOLY entities. It can also generate 3DFACE entities, perpendicular to a POLYLINE for obtain cross... Platforms: Windows, Windows 8, Windows 7, Windows Server

There are two models in this submission.1. trafficpatterns - a simple model of vehicular traffic on four roads all leading to an intersection controlled by a traffic light. It turns green for each of the four paths with specified durations. Tweak the traffic light durations to study how much... Platforms: Matlab
