The classes have some algebraic operators defined, such that the class type T has to be of a numerical type, i.e., float or double. The multiplication methods are implemented based on the BLAS library if an implementation is provided (HAS_BLAS is defined, see BLAS.h). Otherwise, inlined methods are used.
