Because the matrix multiplication is associative; the product can be carried with different order, leading to the same result up to round-off error, MMTIMES usings "optimal" order of binary product to reduce the computational effort (probably accuracy is also improved)
The function assumes the cost of the product of (m x n) with (n x p) matrices is (m*n*p). This assumption is typically true for full matrix.
MULTIPROD is a powerful, quick and memory efficient generalization for N-D arrays of the MATLAB matrix multiplication operator (*). While the latter works only with 2-D arrays, MULTIPROD works also with multidimensional arrays. MULTIPROD...
The project models a Matrix in JAVA with a complete Object Oriented approach, from its values to its access and indices. There are specialized classes for tables(2), cubes(3), and arbitrary(N) dimensions matrices
This directory contains MATLAB functions for the fast multiplication of a Toeplitz matrix times a vector. By using these routines you can avoid storing the entire matrix (using two vectors of lenght n rather than a matrix of size n*n), and also...
This submission defines a generic class of matrix-like objects called MatrixObj and a subclass called DataObj. Objects of the class are capable of behaving as matrices, but whose math operators (+,-,*,,.*,,etc...) and other methods can be...
This recipe adapts the infix operator trick from http://code.activestate.com/recipes/384122-infix-operators/ to give the appropriate behavior with numpy arrays, so you can write A *dot* B for np.dot(A,B)
UPDATE A solution to the...
The main function included in the attached file is called FRAME. The algorithm implemented in this function can be useful in motion analysis (biomechanics, bioengineering). When you know the 3-D position of at least three non-collinear...
Using 'reduce' and 'map', this code shows how a matrix vector multiplication can be reduced to a single loop.
A C++ matrix class for creating matrix objects and easily performing elementary operations between matrix objects including addition, subtraction, multiplication, transposition, and trace.
write_matrix_bin(f,m) saves the matrix "m" in a binary file "f". write_matrix_bin is a lot faster than the built in function save(), and takes up much less diskspace than the old "save -v6" which doesn't use...
Script for the multiplication of linear expressions without coefficient constants. This script returns a polynomial of given expressions. The number of expressions are not restricted and constant may be real or integer.
Example
The JSparse Matrix Package, developed by Philipp GeigenmA?ller during an internship at the prudsys AG in Chemnitz, Germany, is an extension of the well-known Java Matrix Package (JAMA) and allows the use of sparse matrices and related algorithms.
VMatrixLib is a little, handy, Java matrix library which implements a set of utility functions (such as calculus of the determinant of a matrix, calculus of the rank, inverse matrix, and many others..) that anyone who have to use matrices needs.
Open-source Java libraries, supporting generalized smart arrays and matrices with elements of any types (1 bit, 8/16/32/64-bit integers, 32/64-bit floating point values and any other Java types). The libraries contain a wide set of 2D-, 3D- and...
MatrixMenu is a java menu applet, which can build a menu in your web pages with a running matrix like effect in the background and the menu items in the foreground. You can use the write the html code necessary to include the applet in your pages...
tEuroCalc is a easy to use Java applet and can run on all browsers with JDK 1.02 support. This Applet can make all standard operation like addition, deduction, multiplication, division, percentage etc. By using this applet you can convert...
Java editor allows you to edit java code, compile, view errors, run application or applet and much more.
