Description: module to manipulate NxN matrices of real numbers
Math::MatrixReal implements the data type "matrix of reals" (and consequently
also "vector of reals") which can be used almost like any other basic Perl
type thanks to operator overloading.
.
It features many important 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.
.
It allows one to solve linear equation systems using an efficient algorithm
known as "L-R-decomposition" and several approximative (iterative) methods.
.
It 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).
.
Finally, it allows one to solve the eigensystem of a real symmetric matrix,
using Householder transformation and QL decomposition.
