Derivative tools

Functions for calculating derivatives with different methods:

• partial_derivatives.hpp : calculate derivatives using spline interpolation

Utility tools

The l_norm_tools.hpp file contains functions computing the infinity norm. For now, it computes the infinity norm of

• a double: \(\Vert x \Vert_{\infty} = x\);
• a coordinate: \(\Vert x \Vert_{\infty} = \max_{i} (|x_i|)\).
