Function cubic_interpolate


\begin{boxedminipage}{\textwidth} \begin{verbatim}y = cubic_interpolate(x0,y0,x1,y1, & x)\end{verbatim} \end{boxedminipage}

Perform a cubic interpolation between the points $(x_0,y_0)$ and $(x_1,y_1)$, using the cubic function with zero first derivative at $x_0$ and $x_1$. Returns the interpolated $y$ at position $x$, where $x_0 \le x \le x_1$.

x0, y0, x1, y1, x -- real(dp), intent(in)

Return value -- real(dp)
