The Matrix class represents a mathematical matrix. It provides methods for creating matrices, operating on them arithmetically and algebraically, and determining their mathematical properties (trace, rank, inverse, determinant, eigensystem, etc.). The Vector class represents a mathematical vector, which is useful in its own right, and also constitutes a row or column of a Matrix. WWW: https://github.com/ruby/matrix END
