A .zip file contains a series of scripts that were used in the MathWorks webinar "Using MATLAB to Develop Portfolio Optimization Models." The scripts generate 3D efficient frontiers for a universe of 44 stocks with time as the third axis. Additional scripts perform various ex-ante and ex-post... Platforms: Matlab

Demo graphical user interface that finds an unconstrained mean-variance efficient frontier given asset price data. This data can come from Yahoo finance, where you can find the optimial portfolio for any set of assets you choose, or from a supplied Microsoft Access database. Platforms: Matlab

SpectralClustering performs one of three spectral clustering algorithms (Unnormalized, Shi & Malik, Jordan & Weiss) on a given adjacency matrix. SimGraph creates such a matrix out of a given set of data and a given distance function.The code has been optimized to be both fast and memory... Platforms: Matlab

Buying permanent links is best way to boost rating and increase website organic search which brings targeted customers. This backlinks product makes all-in-one forum submission and superb online promotion. It seeds back links from which only the best business reputation grows. The quantity of... Platforms: Windows

FLENS (Flexible Library for Efficient Numerical Solutions) is a C++ library for scientific computing. It can be considered as a very convenient and --- at the same time --- extremely efficient interface for BLAS and LAPACK. But it is much more than this Platforms: *nix

This script generates an efficient and elegant rain/snow effects.The effect is created without the aid of images. You can toggle between rain and snow effect with the change of one variable. Platforms: JavaScript

PHPLinks is an open source project written in PHP for use with MySQL, allowing one to run an extremely efficient Link Farm with full search capabilities. It is a "simulated" search engine in many ways. Platforms: PHP

This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing.The code was initially implemented through vectorization. After discussions with John D'Errico, I realized... Platforms: Matlab

Developed the function after being unable to find a post providing an efficient version of RANDPERM function. Platforms: Matlab

How do you find the shortest path from one point to another in a computationally efficient way? The A* algorithm provides one implementation where the distance to the goal is considered as a heuristic in addition to local weightings, and the best path is recovered without combinatorial complexity. Platforms: Matlab

This is an implementation of [1]. The result is slightly different from website[1], because we apply adjacent neighborhood rather than K nearest neighborhood. The following is an example usage:%complie:(only once)GraphSeg_complie%Read an imageimg = imread('imagesrice.jpg');%segmentation[L,... Platforms: Matlab

This is a simple but efficient tool (GUI) for the visualization of 2 superposed images (2D) from the workspace . You can change the display value of each image with a slider, and you have few visualization modes (red fusion, white/gray fusion, addition of the two images multiplied by their... Platforms: Matlab

Very efficient moving average filter implemented using convolution.Usage:Smoothed Data = movave(Data Vector, Averaging Window Size in Samples)See also: slidefilter.m by the same author Platforms: Matlab

MorkParser is an efficient C implementation of Mozilla's Mork database format reader. It is dependent on Trolltech Qt, but this dependency can be easily removed.Mork is a type of file format used by browsers based on Gecko engine that allows the data manipulation. Platforms: C and C plus plus

This is a tool for K-means clustering. After trying several different ways to program, I got the conclusion that using simple loops to perform distance calculation and comparison is most efficient and accurate because of the JIT acceleration in MATLAB.The code is very simple and well documented,...
