The Fourier transform takes a signal in the time domain and maps it, without loss of information, into the frequency domain. The frequency domain representation is exactly the same signal, in a different form. The inverse Fourier transform(IDFT) maps the signal back from the frequency domain into... Platforms: Matlab

Note that this function do not return EIGEN VECTORS.This function is faster than looping on EIG when eigenvalues must be computed for a large number of matrices. The test shows it can speed up by 10 times Platforms: Matlab

Uses x,y coordinates to produce distance-based spatial weight matrices useful for spatial econometric regressions. The user is asked to input x and y coordinates, as well as a lower and upper bound threshold for the neighborhood.The code is adapted from a previous version by Shawn Bucholtz of the...

You can follow the examples given in the codes, to construct your 2-Dfuction in 2-D Laplace transform domain, insert it into the place of our examples, then you can get the inverse 2-D Laplace transform of your function. Platforms: Matlab

Allows compact representation of block-circulant matrices and fast operations (*,,pinv,etc).Circulant matrices arise in many matrix problems where the underlying mathematical model has rotational symmetry. In many problems, the problem representation is not a simple circulant matrix, but a... Platforms: Matlab

Converts a matrix into a cell array of different sized matrices that make up the blocks. Essentially if one has a matrix M that they wish to store more efficiently in memory/use for function bldiagmult.m (same author), then use cellform = blkdiagconv( M );this is such that using the inbuilt...

Normalizes N-D vectors provided either in one matrix, or as multiple component matrices.NORMVEC normalize vector(s). NORMVEC computes the unit vectors in the direction of the vectors provided. It can process two types of arguments: 1) single matrix of vectors 2) multiple matrices of vector... Platforms: Matlab

GFourier is a plug-in for GIMP; with GFourier, you can use Fourier Analysis, to enhance and recover your images. More specifically, GFourier calculates the Fourier Transform of an image; you can then design and apply some simple filters; later, you can use the Inverse Fourier Transform to... Platforms: *nix

Scalable OpenGroupware.org (SOGo in short) is a groupware server built around OpenGroupware.org (OGo) and the SOPE application server. This project focuses on scalability. We are constantly improving functionnalities and the user experience. So far, we improved the user interface to use AJAX and... Platforms: *nix

Robot4 (tm) is a Robotic Arm Movement program where the arm is moved from a given position to a desired position. The program finds the angles necessary for the desired position. Problem came from NASA. Robot4 is an Inverse Problem example. It wants to solve how to move from starting point... Platforms: Windows, Windows 8, Windows 7, Windows Server

recvnet is the inverse of telnet. Instead of connecting to some host, it listens on a port for incoming connections. When a connection is made, it works as usual.

Math::Matrix can multiply and invert Matrices. The following methods are available: new Constructor arguments are a list of references to arrays of the same length. The arrays are copied. The method returns undef in case of error. $a = new Math::Matrix ([rand,rand,rand],... Platforms: *nix

Matriosity generates 12-tone matrices for use in serial music. You can enter a prime row as either letters or numbers and Matriosity will do the rest, generating the matrix as letters or numbers and also analyzing the prime forms of the dyads, trichords, tetrachords, and hexachords. Matrices... Platforms: Mac
