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. 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.
