This module implements the data type "matrix of reals", which can be used almost like any other basic Perl type due to OPERATOR OVERLOADING, i.e., $product = $matrix1 * $matrix2.

It also 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.

This module allows to solve linear equation systems using an efficient algorithm known as "L-R-decomposition" and several approximative (iterative) methods.
