The Generalised Adaptive Fast-Fourier Evolver (GAFFE) toolbox is a framework that greatly simplifies the solution of complex partial differential equations (PDEs) in an adaptive manner.
By default both the step-size and the mesh adapt to the problem at hand to optimise the speed of execution for a given nominal target accuracy.
The technique is N dimensional and can therefore be used to model diverse problems such as...
This program creates 3-dimensional rocks comprised of triangles by taking the convex hull of a sphere distorted with Perlin noise.
It outputs these rocks in OpenGL code. It requires the free CGAL library from http://www.cgal.org/ to...
Quickly and easily create 2d and 3d plots of fMRI data. Industry standard brain plotting programs are great for producing publication-quality images of brain data. However, these tools are often very slow. This suite of tools provides a means...
This function converts an MATLAB 2-dimensional array (matrix) which can be numerical or a cell array, into proper formated LaTeX code. This utility is actually the GUI representation of M.Koehler matrix2latex code.
This function plot a colored 3-dimensional line of a set of given points. The plot varies its color in a form, x axis as red, y as green and z axis as blue. So basically if the plot proceeds in x-axis it will colored as red, if proceed...
The program is an ordinary m-file the matrix g(*,*) can be used to punch in the metric values in terms of symbolic variables x1,x2,x3,x4(co-ordinate axes) The program first computes the Affine connection(Christoffel symbols) stored in...
Tabular Expression Toolbox
Tabular Expressions (also called "tables") provide a precise and concise way to represent mathematical conditional expressions. Tables have been shown to be useful in the documenting and analysing of...
PCG Preconditioned Conjugate Gradients Method is a replacement of the standard built-in PCG code. Two new options are implemented: 'flex' and 'null'. The 'flex' option changes the standard PCG algorithm into the flexible one. It allows using...
Normalized mutual entropy provides a measure of the diversity of a two dimensional matrix. It takes mutual entropy and normalizes for the marginal entropy of the variable of interest (column variable in the code). See screen shot or embedded...
Two simple functions that exports a triangulation/tetrahedralization in standard format (as provided by delaunay.m) to the vtk-file format. Either point or cell data can be exported additionally. This is useful for the visualization of...
MIDAS 2010 is a package developed in the Canadian Light Source for 2D spectroscopic analysis and data exploration of time resolved infrared spectra.
Features: - calculate and plot synchronous and asychronous 2D spectra, and one...
HARMASYLLABLESEG - Segments a signal stored in a WAV file into individual syllables. Also graphs the spectrogram and signal with syllables highlighted in red to show what parts of the signal contain syllables.
INPUT:
-...
The demo uses one possible implementation of hooking up a SimEvents model with 3D animation using Simulink 3D Animation.
A simple model of an entity generation is created in SimEvents. This entity generation is sampled in time to...
AQUILA is a MATLAB toolbox for the one- or two dimensional simulation of the electronic properties of GaAs/AlGaAs semiconductor nanostructures. The program solves for a user-defined structure the one- or twodimensional Schroedinger- and...
The note explains in detail how to apply the Matlab 2-dimensional FFT for filtering of two-dimensional signals, e.g. images. It is shown how to connect the output from fft2 to the actual Fourier transform of the signal, and in particular how...
Input parameters p : odd prime number deg: positive integer (default value = 1)
Output is a (p^deg+1) by (p^deg+1)/2 matrix E
When deg > 1, the communication toolbox is required
A collection of...
FINDARRAY Find one array within another I = FINDARRAY(A,B,'first') for the array B returns an index array of the same size as B containing the smallest absolute index in A for each element of B which is a member of A and 0 if...
This program will assist the user to visualize the foot print of type2 fuzzy membership functions in 3 dimensional mode.
This module is used to obtain Canada Post shipping quotes for Ubercart. It interfaces with Canada Post's "SellOnline" service (http://sellonline.canadapost.ca) to quotes directly from the Canada Post server. Works for both domestic and...
Inputs: 1. a 1 dimensional array of drug concentrations 2. the corresponding m x n array of responses Algorithm: generate a set of initial coefficients including the Hill coefficient fit the data to the 4 parameter... |
