CSMV calculates distances from a given set of points to a set of linear segments
SYNOPSIS: [squared_distances_to_segments I]=csmv(P,R,Q,to_plot) [squared_distances_to_segments I]=csmv(P,R,Q,...)
INPUT P,R : arrays of coordinates of 2n segment endpoints (i.e., if there are n segments considered in p-dimensional Euclidean space, than P and R are n-by-p matrices); the sizes of P and R should...
This function can be used to obtain smooth function by increasing number of points of the function.
Function to find the minimum distance loop from given set of points. This function uses the distance formula to genrate a minimum distance loop. function mindist = minimumdistance(X,Y,x,y) X = X coordinate vector Y = Y...
A line of connected straight sections is fitted to a 2D-cloud of data points. The sections are described by the coordinates of their endpoints. No toolbox required.
You have 2 points, and you want N number of points between these 2 points. It's like making a line between 2 points. It takes start and end points, and the number of points you want in between.

Returns the convex hull (separated into upper and lower chains of vertices) and the diameter (farthest pair of points), given input consisting of a list of 2d points represented as pairs (x,y). The convex hull algorithm is Graham's scan, using a...
The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with...
Fits an ellipsoid into a 3D set of points, allows some constraints, like orientation constraint and equal radii constraint. E.g., you can use it to fit a rugby ball, or a sphere. 'help ellipsoid_fit' says it all. Returns both the algebraic...
VERT2CON - convert a set of points to the set of inequality constraints which most tightly contain the points; i.e., create constraints to bound the convex hull of the given points
[A,b] = vert2con(V)
V = a set of points,...
This program implements the iterative algorithm in Khachiyan's paper "Rounding of Polytopes in the Real Number Model of Computation" to approximate the minimum volume ellipsoid circumscribing a non-degenerate set of points in arbitrary...
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...
http://simulations.narod.ru/ The diffusion is simulated as set of points with random step each frame of time. Looks like brownian motion. Step of point can be estimated from diffusion equation: dn/dt=D*(d2n/dx2+d2n/dx2) then...
