Non Convex Polygon

Leverage the power of nodewords custom pages to set the page title using wildcard paths and global tokens. Great for tough-to-reach page titles in Views, Panels, and other non-node paths!The value proposition:You're frustrated with your page titles. You've never been able to put a decent...

The function "Return_points_polyg_direct" finds the subset of an arbitrarily large set of 2D points. This subset defines the convex polygon that includes all above points. The function accounts for aligned or identical points.Below is an example of how to use the function with 100 random 2D... Platforms: Matlab

The intention is to make a more flexible and more general function than the Matlab function dblquad. Especially the domain may be given in a more general way, it may be a circle, a rectangle, or any convex polygon. Also different methods may be used. Q = DOUBLEINTEGRAL(FUN, DOMAIN, PARAM) FUN is...

Calculate the distance from a point to 2-D polygon, and the point on the polygon closest to the point.This is based on the function made by Michael Yoshpe. Also include the test suggested by Eric Schmitz. Platforms: Matlab

Calculates point position in 2D polygon: inside, outside, is a vertex and on the edge. Platforms: Matlab

This provides a GUI to simulate navigation of a non-holonomic vehicle in from any location and orientation with the designated area to a fixed parking location. The controller is based on the use of Interval Type-2 Fuzzy Sets (FOU=[0 3 0]) which can be reduced to Type-1 Fuzzy Sets, if FOU is... Platforms: Matlab

NUMREGPOLY Number of Intersection Points and Regions Made By The Diagonals of a Regular Polygon [A,B,I,R]=numregpoly(N) for integer n returns the following: A: Vector of number of points inside the regular n-gon other than the center where exactly k lines meet B: Vector of number of k-tuples of...

Given an input primal gear, the toolbox compute its associated dual gear together with the associated distance between the gear centers.The gears are described as a discretized polar curve. The dual gear is solved by a numerical integration of the non-sliding condition. The distance between the... Platforms: Matlab

This function NLMF performs Non-Local Means noise filtering of 1D signal, 2D grey/color or 3D image data. The function is partly c-coded for cpu efficient filtering. Suitable for almost every image data type such as MRI, CT and normal photos.Warning !, Image filtering removes noise, but important... Platforms: Matlab

solvesimul.m can be easily adapted to solve more equations but as it stands it will solve 2 unknowns in 2 equations (1 non-linear and one linear).To solve equations of this form... a*x + b*y = A (1) a1*x^2 + b1*y^2 = B (2)...with fsolve (used by solvesimul.m) you need to rewrite them so that they...
