Pareto surface navigator This builds a navigation GUI for navigating n-dimensional convex Pareto surfaces interactively. It requires linprog from theoptimization toolbox, but can probably be replaced easily with a free version. The linear programs solved during navigation are very small and easy. It is assumed that all...

Regular Polygons Let d < N be a positive integer and define p = N/d. Let y_{1} be a point on the unit circle. Let R be clockwise rotation by the angle t = 2*pi/p. The generalized regular polygon {p} is given by the points y_{i+1} = R * y_{i}, and edges between points i and i+1.Example:polygon(9, 4, 1);

mask2poly This functions goal is to find a polygon which enclosures a user supplied mask. It's a kind of a complementary of Matlab poly2mask function. The difference is that all contour points are returned- without missing points for linearly related points. In order to get a 100% complementary of...

hullfit When interpolating on a given data set, convhull is used to set the boundaries of the interpolation area. Because convhull only minimizes the outline length, there might be interpolation lines which are unwanted (see figure).hullfit tries to minimze the polygon area instead resulting in a hull...

circum circle Accepts a list of x and y coordinates. First, we find the smallest circumscribing polygon from this list (convhull). Finally, we use this polygon's coordinates to find the smallest circumscribing circle. We find the circle by minimizing the distance of the circle center to the polygon's...

Representing Polyhedral Convex Hulls by Vertices or (In)Equalities This submission contains VERT2LCON and LCON2VERT, which will find the linear constraints defining a bounded polyhedron in R^n, given its vertices, or vice versa. They are extensions of Michael Kleder's VERT2CON and CON2VERT functions that can handle cases where the polyhedron is not solid in R^n,...

2D polygon interior detection This function tries to improve the slow Matlab INPOLYGON function.There are few other fast codes on FEX (e.g., by Darren Engwirda). After exploring many different ways, I come to the conclusion that Darren Engwirda's approach is close to optimal. So here you'll find a general method that share...
