exp — Exponential


\begin{rail}
Exp : 'exp' '(' ( Scalar \vert Matrix ) ')' ;
\end{rail}
exp returns e raised to the power of the argument. If the argument is a matrix, then an element-by-element operation is performed. If the argument is complex value, z , then the result is:

eℜ(z)cos(ℑ(z)) + jeℜ(z)sin(ℑ(z))
