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. \\
The complex derivative of $x = a + jb \in \complex$, $a,b \in \reals$, is defined as
\begin{equation}
%\label{eqn:eqn1}
Dx = \frac{dx}{da} + j\frac{dx}{db}.
\end{equation}
