Description

This block realizes the following nonlinear function :

\begin{eqnarray}
y=f\left(u\right)=4\;R\;u(1-u)
\end{eqnarray}


where R is a vector of parameters (first regular input port), u a vector of inputs (second regular input port) and y the vector of outputs. The parametrized plot according to the parameter R is shown in Fig.1.
