MulticomplexNumbers

A Julia package for representing multicomplex numbers and performing multicomplex algebra.

Multicomplex numbers are a generalisation of complex numbers, recursively defined to contain multiple imaginary numbers, $i_1$, $i_2$ etc. Unlike Clifford algebras, these numbers commute, i.e. $i_1i_2=i_2i_1$.
