Iterations

Large Database Backup is a PHP class can be used to backup large MySQL databases into multiple files. It can list the tables of a given MySQL database and generate SQL statements to create and insert records with the current values of the table rows, as if it was creating a new database. The... Platforms: *nix

DateTime::Astro::Sunrise is a Perl DateTime extension for computing the sunrise/sunset on a given day. SYNOPSIS use DateTime; use DateTime::Astro::Sunrise; ^ my $dt = DateTime->new( year => 2000, month => 6, day => 20, ); my $sunrise = DateTime::Astro::Sunrise ->new(-118,33,undef,1);... Platforms: *nix

JPEG Fit is a PHP class that can be used to optimize images to fit within a given file size limit. The project takes a picture in any format supported by the GD library and generates a JPEG picture with the maximum quality factor that makes the picture file size not exceed a given limit. This... Platforms: *nix

One of the ultimate time-wasting applications, Fractality is a toy and/or tool for creating polygonal fractals. Like geometric fractals, polygonal fractals are repetitive patterns following certain mathematical algorithms. Yet polygonal fractals are simpler, usually more symmetric, and often much... Platforms: Mac

JPEGtoASCII is an appllication that will help you convert any JPEG file into blocks of characters. To load a picture for interpretation, choose the File->Open menu or File->New then drag a picture file onto the window. The Characters Library is a string of characters that JPEGtoASCII will use to... Platforms: Windows

QuickMAN is a very fast Mandelbrot image generator. ASM-optimized code reaches over a billion iterations per second on fast CPUs. Now you can make use of this handy and simple piece of software to generate the images you want. Platforms: Windows

Cryptnos will provide users with an application that will help you generate strong, pseudo-random passwords using cryptographic hashes. Cryptnos combines a unique "site token" such as a website domain name with a master password and runs this data through a cryptographic hash algorithm to... Platforms: Windows

Frond is a cross platform fractal viewing application written in Java. Frond allows you to zoom in to any area of the fractal with unlimited undo and redo capabilities and adjust amount of iterations to maximise detail. Platforms: Windows, Mac, Linux

op4j is a developer happiness tool. Its aim is to reduce the amount of similar lines of code needed to do every day tasks in our code by providing an operator chaining tool to perform easy iterations on lists, OGNL evaluation, data type conversion... Platforms: Windows, Mac, Linux

Depth Conversion uncertainty analysis for the oil and gas industry. Incorporates cross-validation and multiple iterations. Platforms: Windows, Mac, Linux

This script contains a simple, easy to use wrapper function for doing quick tests of your functions using the timeit module.The timeit module provides an easy way of testing the performance of your Python code by running it in many iterations and averaging the timings. However it is not very... Platforms: Windows, Mac, *nix, Python, BSD Solaris

Randomized integer range iterator script iterates over all values of a range in random order. Platforms: Windows, Mac, *nix, Python, BSD Solaris

It can handle iteration for all permutations, combinations, subsets and tuples.This is useful when the results of perms or nchoosek are too large to hold in memory but the number of iterations is feasible.Vectors are ordered according to number of elements and lex. if the length is the same, they... Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

QuickSkin is a template engine that was designed to support web based applications of any size. It is particularly suited to large scale applications like Content Management Systems.Common template engines work like the following: Your PHP script specifies an HTML template and assigns some... Platforms: BSD Solaris

EDFT (Extended Discrete Fourier Transform) algorithm produces N-point DFT of sequence X where N is greater than the length of input data. Unlike the Fast Fourier Transform (FFT), where unknown readings outside of X are zero-padded, the EDFT algorithm for calculation of the DFT using only... Platforms: Matlab

The function LMFsolve.m serves for finding optimal solution of an overdetermined system of nonlinear equations in the least-squares sense. The standard Levenberg- Marquardt algorithm was modified by Fletcher and coded in FORTRAN many years ago. LMFsolve is its essentially shortened version... Platforms: Matlab

The script quasi_newton_dfp.m optimizes a general multi variable real valued function using DFP quasi Newton method. During the iterations if optimum step length is not possible then it takes a fixed step length as 1. For the theory any good book on optimization techniques can be consulted. This... Platforms: Matlab

The Particle Swarm Optimization Research Toolbox was written to assist with thesis research combating the premature convergence problem of particle swarm optimization (PSO). The control panel offers ample flexibility to accommodate various research directions. After specifying your intentions,... Platforms: Matlab

It's a function that finds the minimum value of a two variables objective function with a deterministic zero order algorithm: simplex method. The input variables are:-fun: inline function of the objective function-init_point: initial point for the simplex method-step_size: initial dimension of... Platforms: Matlab

This is the iterative 2D Minimum Entropy Deconvolution implemented according to an iterative method in the original paper:R.A. Wiggins, Minimum Entropy Deconvolution, Geoexploration, vol. 16, Elsevier Scientific Publishing, Amsterdam, 1978. pp. 21d-deOCt35.This also works applying the 1D MED when... Platforms: Matlab
