Shown here is only the 7-parameter version of the Helmert transformation
but of course this obviously also extends to the 14-parameter version and
combinations of the two.
\section{Including velocity}
Following the notation above we introduce the input, $V_A$ and output $V_B$ velocity vectors and the translation rate vector $\dot{T}$, rotation rate matrix $\dot{\matr{R}}$, and the scale rate factor $\dot{c}$.


\begin{equation}
V_B = V_A + \dot{T} + \dot{c} \dot{\matr{R}} P_A
\end{equation}
