This program estimates the background (or baseline) of optical spectra by the polynomial minimizing a cost function. If the cost function was quadratic, the solution is the least squares estimation, which is not appropriate in this problem. Instead, we need to use of non-quadratic cost function...

A fast customizable function for locating and measuring the peaks in noisy time-series signals. Adjustable parameters allow discrimination of "real" signal peaks from noise and background. Determines the position, height, and width of each peak by least-squares curve-fitting. It can find and... Platforms: Matlab

mwavepy is a compilation of functions for microwave/RF engineering. It is useful for things such as calibration, data analysis, data acquisition, and plotting functions. Being that it has been built around my specific needs as a graduate student, it is far from complete, but non the less pretty... Platforms: *nix

Unstructured meshes . Higher order finite elements . Galerkin and Least squares, including discontinuous... Platforms: *nix

PDL::Fit::LM is a Levenber-Marquardt fitting routine for PDL. Currently, only Levenberg-Marquardt fitting is implemented. Other procedures should be added as required. For a fairly concise overview on fitting see Numerical Recipes, chapter 15 "Modeling of data". SYNOPSIS use PDL::Fit::LM;... Platforms: *nix

Proc::BackOff::Linear is a generic module meant to be directly inherited from and then modified by overloading the calculate_back_off object method. SYNOPSIS Usage: use Proc::BackOff::Linear; my $obj = Proc::BackOff::Linear->new( { $slope => 5, x => count, b => 0 ); # sequence would be... Platforms: *nix

Gravers Football Squares project is a Web-based version of Superbowl Squares. Gravers Football Squares was created so multiple people could enjoy Football Squares during the Superbowl or any other major game that may be going on. Ive been using it for the last few years, and thought I would... 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...

Place tiles on the board to try to create squares. If the tile touches another tile, the sides that touch must have the same symbols. When you create a square of four tiles, you receive bonus points. Needs The Lobby from www.tams11.com in order to play against other players. Platforms: Windows

Linear Program Solver is a small, simple, very easy to use tool specially designed to help you solve linear programming models. This tool offers: informative solving reports, extended sensitivity analysis, mixed integer models engine. LiPS supports MPS format and simple LP format (like... Platforms: Windows

Linear Interpolation Calculator is a free solution that gives you the possibility to interpolate between values to arrive to the correct intermediate result. Linear interpolation has many uses usually in steam tables to find the unknown value. Platforms: Windows

It needs a set of 3D points, equal radii constraints and orientation constraint to fit an ellipsoid into a 3D block object Requirements: - MATLAB 7.7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

This script defines the Matrix class, an implementation of a linear algebra matrix. Arithmetic operations, trace, determinant, and minors are defined for it. This is a lightweight alternative to a numerical Python package for people who need to do basic linear algebra. Vectors are implemented as... Platforms: Windows, Mac, *nix, Python, BSD Solaris

This is a simple way of expressing non-linear scales (such as decibels) in python. In stead of:gain = 10 ** (12/10.)Use Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script allows you to run a linear equations solver using eval and built-in complex numbers.One could add one more line to insert '*' where needed, i.e. "100x" -> "100*x", add some input validation, in particular check whether the equation is actually linear and not quadratic or cubic, and...
