\newcommand{\complex}{\mathbb{C}}  Here we provide a definition for the 'complex' derivative of a real-valued function $f : \complex^n \to \reals$ with respect to its complex variables. \\  %Let $x = a + jb \in \complex$ be a complex number, where $a \in \reals$, and $b \in \reals$. \\  The complex derivative of $x = a + jb \in \complex$, $a,b \in \reals$, is defined as   \begin{equation}  \label{eqn:eqn1}
