math/p5-Math-MatrixReal,

*Perl module for performing operations on real matrices*

**Branch:** pkgsrc-2009Q2,

**Version: **2.05nb1,

**Package name:** p5-Math-MatrixReal-2.05nb1,

**Maintainer: **pkgsrc-usersMath::MatrixReal - Matrix of Reals

This module includes many important matrix operations and methods:

matrix norm, matrix transposition, matrix inverse, determinant of a

matrix, order and numerical condition of a matrix, scalar product of

vectors, vector product of vectors, vector length, projection of row

and column vectors, a comfortable way for reading in a matrix from a

file, the keyboard or your code, and many more.

Systems of linear equations may be solved using an efficient algorithm

known as "L-R-decomposition" and several approximative (iterative)

methods. The Householder transformation and QL decomposition for the

determination of the eigensystem of a real symmetric matrix are also

implemented.

The module also features an implementation of Kleene's algorithm to

compute the minimal costs for all paths in a graph with weighted edges

(the "weights" being the costs associated with each edge).
