Description

template<class Scalar, int numSamples = 2>
class Dumux::Spline< Scalar, numSamples >

This class implements a spline $s(x)$ for which, given $n$ sampling points $x_1,\dots ,x_n$, the following conditions hold

$$\begin{array}{rl}s(x_i)& =y_i\mathrm{\forall }i\in \{1,\dots ,n\}\\ s^{\prime }(x_1)& =m_1\\ s^{\prime }(x_n)& =m_n\end{array}$$

for any given boundary slopes $m_1$ and $m_n$. Alternatively, natural splines are supported which are defined by

$$\begin{array}{rl}s(x_i)& =y_i\mathrm{\forall }i\in \{1,\dots ,n\}\\ s^{″}(x_1)& =0\\ s^{″}(x_n)& =0\end{array}$$
