The Pagerank Algorithm

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 dimensions.It is basically like Nima Moshtagh's MinVolEllipse...

Demonstrates a way to implement the LSM algorithm.This is done on a example from the book of Astrom and Wittenmark, Adaptive Control, 2nd ed

This is an implementantion of the Gauss algorithm for block tridiagonal systems. The blocks must all be the same size. This approach requires for loops so is of value when the matrix is large. Ideal for solving 1D BVPs using finite element or spectral methods.

This is a simple function to prevent massive clipping and possible hearing damage in case the audio algorithm you were working on happens to be unstable or has too much gain.This is not a limiter; it just scales back the entire signal if necessary to ensure that the maximum peak value is no more...

SimPartCohImg uses 'sum over the source' algorithm to compute the images produced by partially coherent (i.e., non-fluorescent) imaging systems such as phase microscopes and optical lithography systems. This is perhaps the first freely available code for this purpose. Total image is the sum of...

A reimplementation of the CSSR algorithm of Shalizi et al. Extends the input data from discrete to continuous clustered by way of a novel discretisation scheme. Allows users to infer optimally predictive hidden Markov models from their data, either supplied or generated by the code. Calculates...

This is a multiparticle version of the CMorph algorithm previously submitted. The algorithm takes the gradient of the image, and then applies decreasing thresholds and fill operations to attempt to identify objects. One it has found the objects, it attempts to pair them up with objects in the...

Thus, this work offeres a sequential version of the LSI algorithm(SLSI). Its main difference from the existing algorithms is that thedimension of space is not fixed and dynamically changes toensure a given level of relative approximation error of a matrix ofobservations. Experiments with a real...

Sparsity Recovery by Iterative Orthogonal Projections of Nonlinear MappingsA new regularization method for sparse representation based on a fixed-point iteration schema which combines two Lipschitzian-type mappings: an orthogonal projector and a nonlinear one for sparsity promotion.

Using the same algorithm as our Flanger plugin, this plug-in adds a unique feature to the original effect: you can smoothly transform it into a stereo flanging effect with a single slider. Push the 'stereo' slider of the user interface and hear the difference: the effect is turning around you...

Lzip is a lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses better than bzip2, which makes it well suited for software distribution and data...

This creates a random heightfield with the fault algorithm. It takes a somewhat lengthy time to finish increasing a lot with the resolution and number of blocks of the finished file. It saves it as a jpeg file. The fault algorithm is where the computer makes a random ax+by=c line and everything...

Hashr is a simple web utility that tranforms any given string into an cryptographic hash of the chosen algorithm. You can choose between 40 or more different algorithms. It was written in PHP and some javascript effects. What is it for? Well, mainly it was developed by me, for me. It's a tool I...

pyrsync is a Python module which implements the rsync algorithm, written in pure Python. It is not a wrapper for rsync, but a set of functions which apply full rsync functionality through Python. The original rsync specification calls for the use of an MD5 hash, which the developers of this...

Algorithm::PageRank::XS is a Perl module that implements a simple PageRank algorithm in C. The goal is to quickly get a vector that is closed to the eigenvector of the stochastic matrix of a graph. Algorithm::PageRank does some pagerank calculations, but it's slow and memory intensive. This...
