template struct mrpt::math::RobustKernel<rkLeastSquares, T>¶
No robust kernel, use standard least squares: rho(r) = r^2.
#include <mrpt/math/robust_kernels.h> template <typename T> struct RobustKernel<rkLeastSquares, T> { // fields T param_sq = 1; // methods T eval(const T r2, T& out_1st_deriv, T& out_2nd_deriv); };
Fields¶
T param_sq = 1
The kernel parameter (the “threshold”) squared [Not used in this class, provided for consistency with the other classes].
Methods¶
T eval(const T r2, T& out_1st_deriv, T& out_2nd_deriv)
Evaluates the kernel function for the squared error r2 and returns robustified squared error and derivatives of sqrt(2*rho(r)) at this point.
