Acupuncture Points

This is a module that makes use of the User Points module API.It allows you to "evaporate" user points from all your users over time, so they need to come back to your site and be active to keep accumulating more points

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a...

This function can be used to obtain smooth function by increasing number of points of the function.

isParetoSetMember returns the logical Pareto membership of a set of N points in K dimensions. It takes as input a N-by-N matrix and return a N-binary-array, denoting for each of the N points, whether it is Pareto (1) o not (0).The concept of Pareto dominance considered herein is the standard...

sel_and_del Interactively select and delete points from a line object using mouse input. Left-click selects the point closest to the click and Right-click unselects it. The selected points are highlighted with a black square. The selection process is stopped by hitting any keyboard key when the...

VEC = PLANENORMVEC(PT1,PT2,PT3) calculats the normal vector of a plane that includes three points PT1, PT2, and PT3. When the plane is expressed as ax + by + cz = 1, VEC(1) = a, VEC(2) = b, VEC(3) = c. Points should be a 1 x 3 vector, specifying x, y and z values for each column.(Example)p1 =...

A Zipped file has eight files which are related to Demo2D.m and Demo3D.m. The Demo2D removes the points in 2D-space and also find out non-overlapped points in their strongest magnitude order. The Demo3D does it in 3D-space. The core file is remove_overlapregions_kd.m. Furthermore we used k-D...

GSP is a graphical user interface which takes x and y points as inputs, along with the order m, then outputs mth order splines between each of the x points. In most cases additional constraints are to be entered as well. Example: Input: x points : [1 2 3 4] y points : [2 7 -1 5] Order : 2 *One...
