Parallax is very cool three-dimensional effect. d-deDUCloserd-deDt stars will appear to move faster while more d-deDUdistantd-deDt stars move slower. This is achieved with transparent background /examples/images and percentage positioning. Downloads include Photoshop (.psd) file. Platforms: JavaScript

Some curve fitting or smoothing tools can benefit from knowledge of the noise variance to expect on your data. Kalman filters use this information, also some spline fitting tools. So I wrote a function to extract the noise variance from a signal vector. It also works on any specified dimension of... Platforms: Matlab

This version has been developed for open surface.Differently from crust based algorithm does not ensure a tight triangluation and sometimes self-intersecant triangles are generated, it is also generally slower. The final surface may need some repair work which this utility does not offer.But... Platforms: Matlab

Like histc but for n-dimension.Unlike the other nd histogram http://www.mathworks.com/matlabcentral/fileexchange/3957 beside counting, this function returns also the location of points in the bins. Coded entirely in Matlab (no mex required). Speed slightly slower (but quite decent).User can data... Platforms: Matlab

Simple program that shows how much difference it makes to optimize your code using the profiler tool.However, transfering the code from this M file into an GUI shows that the fasted algorithm (3) runs 10 slower than algorithm (4). Platforms: Matlab

divisor(n) : row vector of all distinct divisors of a positive integer N, including 1 and N.Remark: This function uses the default factor() routine in Matlab and hence is limited to input values up to 2^32. However if factor() routine does get updated for larger integers, this function will still... Platforms: Matlab

The program uses fft and calculates the DCT.This is relatively slower than the original DCT [Built-in], but this is open source DCT Implementation. Platforms: Matlab

it's useful to see how the mean and the standard deviation change when you use more samples to calculate it.The Array can contain NaN's but it's slower than cumstat (File ID: #26899) because it contain a for-loop Platforms: Matlab

VChooseKR(V, K) creates a matrix, which rows are all combinations created by choosing K elements of the vector V without order and with repetitions.INPUT: V: Array of class DOUBLE, SINGLE, (U)INT8/16/32/64, LOGICAL, CHAR. Prefer (U)INT8 or (U)INT16 for speed. K: Number of elements to... Platforms: Matlab

VChooseKRO(V, K) creates a matrix, which rows are all permutations created by choosing K elements of the vector V with order and with repetitions.INPUT: V: Array of class DOUBLE, SINGLE, (U)INT8/16/32/64, LOGICAL, CHAR. Prefer (U)INT8 or (U)INT16 for speed. K: Number of elements to choose.OUTPUT:... Platforms: Matlab

**Background**This is a MATLAB version of AUTO, where we have integrated AUTO into MATLAB via mex functions.This toolbox is aimed at researchers familiar with AUTO, but also engineers that would like toapply these techniques. One of the biggest reasons why Dynamical Systems Theory is not... Platforms: Matlab

Use this code to simulate basic microstructure evolution. This is quite an old code. Will post the updated code in 2D and 3D shortly. This version uses wrap boundary condition and the computation is a bit slower as against the new code. However, I am making some changes to the newer versions. So,... Platforms: Matlab

Little more than syntactic sugar for nchoosek, this small but surprisingly controversial function returns the number of (ordered) n-tuples of non-negative integers adding up to k, and if supplied a second argument, a listing of them. As an alternative to downloading, just cut and paste the... Platforms: Matlab

DELETE OBJECT DELOBJECT( H ) deletes the object with handle h, but is more forgiving than DELETE: when h is empty, zero or not valid, no action is taken. Additionally, DELOBJECT enables deletion of multiple handles at the same time: - H can be an array of handles; all objects are deleted. - H... Platforms: Matlab

A MEX file to calculate a GUID. A Globally Unique Identifier or GUID is a pseudo-random number used in software applications. Each generated GUID is "statistically guaranteed" to be unique. This is based on the simple principle that the total number of unique keys ( or ) is so large that the... Platforms: Matlab

The main script to start the GUI is 'ring.m'. The first GUI will ask for dimension inputs and color. After filling in this information, a second GUI is used to design the ring cross-section. This cross-section is based upon setting up the inner edge of the ring (i.e., finger hole) for the... Platforms: Matlab

This function is an adaptation of a demo published by Steven Lord that let you add a slider to an axes. This function shows you how to set up a slider in a figure that will scroll through tiled axes.This functionality is very usefull in situations where you have a lot of information to plot but...

SiteSpeed measures the speed of your website and displays the results in 7 comprehensive graphs.How long do your visitors have to wait? Is your webserver becoming slower? Are your pages too big? Is your website fast even for remote visitors? Install SiteSpeed and find out. Platforms: PHP

If you want math forumals on your website and dont want the page to load 1 second slower, this is the plugin for you. This is an optimized version of two other latex plugins. It is easy to use and the Latex syntax gives you alot of examples how to write nice latex.This plugin does not allow you... Platforms: PHP

Alchemy is a research project that allows users to compile C and C++ code that is targeted to run on the open source ActionScript Virtual Machine (AVM2). The purpose of this preview is to assess the level of community interest in reusing existing C and C++ libraries in Web applications that run... Platforms: Mac
