Usage

PrimitiveComponents.TestPolynomial()

\[ \begin{equation} \left[ \begin{array}{c} \mathrm{connect}\left( source_{+}y(t), poly_{+}u(t) \right) \\ \mathtt{source.y}\left( t \right) = ifelse\left( \mathtt{source.start\_time} < t, ifelse\left( t < \mathtt{source.duration} + \mathtt{source.start\_time}, \mathtt{source.offset} + \frac{\mathtt{source.height} \left( - \mathtt{source.start\_time} + t \right)}{\mathtt{source.duration}}, \mathtt{source.height} + \mathtt{source.offset} \right), \mathtt{source.offset} \right) \\ \mathtt{poly.y}\left( t \right) = \mathtt{poly.c0} + \mathtt{poly.c1} \mathtt{poly.u}\left( t \right) + \left( \mathtt{poly.u}\left( t \right) \right)^{2} \mathtt{poly.c2} + \left( \mathtt{poly.u}\left( t \right) \right)^{3} \mathtt{poly.c3} \\ \end{array} \right] \end{equation} \]
