The Math::VectorReal' package defines a 3D mathematical "vector", in a way that is compatible with the previous CPAN module ath::MatrixReal'. However it provides a more vector oriented set of mathematical functions and overload operators, to the atrixReal' package. For example the normal perl string functions "x" and "." have been overloaded to allow vector cross and dot product operations. Vector math formula thus looks like vector math formula in perl programs using this package.
