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.
derivative complex derivatives of functionals. \\
Let $x = a + jb \in \complex$ be a complex number, where $a \in \reals$, and $b \in \reals$.
\\
The derivative of x is defined as
\[
Dx = \frac{dx}{da} + j\frac{dx}{db}.
