Matrix Based

Using 'reduce' and 'map', this code shows how a matrix vector multiplication can be reduced to a single loop.

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...

This script presents you three ways to calculate a distance matrix out of a list of n-dimensional points using scipy.

DHTML / CSS based line graph script allows you to represent line graphs using only DHTML and CSS.Unlike an applet based solution, this loads fast and blends in with the rest of the page. You can even use a transparent background for it.


Platforms: JavaScript

This DHTML script renders the Matrix effect on any short piece of text. It works in both IE4 and NS6 , and downgrades well with the rest.


Platforms: JavaScript

This is a purely DHTML/ CSS based Pie Graph script. It loads fast and blends in with the rest of the page. You can even use a transparent background for it.


Platforms: JavaScript

This vertical bar graph is done completely using DHTML and CSS. Unlike an applet based solution, this loads fast and blends in with the rest of the page. You can even use a transparent background for it.

[h,varargout]=plotColumns(data,varargin)plots columns of a matrix as if each column is a time seriesUSAGE:plotColumns(data);[h] = plotColumns(t,data);[h] = plotColumns(t,data,{colors});[h] = plotColumns(t,data,'plotopt');[h] = plotColumns(...,'plotopt');[h] = plotColumns(...,{colors});


Platforms: Matlab

The function generates sequency(Walsh) ordered Hadamard matrix useful for image processing, signal processing, genetic algorithms etc.

CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h). If 'x' and 'h' are row vectors,...
