Detailed Description

Natural cubic splines class.

Definition at line 91 of file trajectory.h.

Constructor & Destructor Documentation

Spl_cubic::Spl_cubic ( )
inline

Definition at line 94 of file trajectory.h.

Spl_cubic::Spl_cubic ( const Matrix pts)

Constructor.

Parameters
ptsMatrix containing the spline data.

The first line of the Matrix contain the sampling time Second line contain data (sk) to create spline i. Third " " i+1. on Nth line i+N.

The spline has the following form:

\[ s = A_k(t-t_k)^3 + B_k(t-t_k)^2 + C_k(t-t_k) + D_k \]
