o2scl::interpm_neigh< vec_t > Class Template Reference

Nearest-neighbor interpolation in arbitrary number of dimensions. More...

Detailed Description

template<class vec_t>
class o2scl::interpm_neigh< vec_t >

This class performs nearest-neighbor interpolation on a multi-dimensional data set specified as a series of scattered points. The function set_data() takes as input: the number of dimensions, the number of points which specify the data, and a "vector of vectors", e.g. std::vector<std::vector<double> > which contains the data for all the points.

void o2scl::interpm_neigh< vec_t >::set_data ( size_t  dim, size_t  n_points, vec_vec_t &  vecs  )

inline

The object vecs should be a vector (of size dim+1) of vectors (all of size n_points). It may have any type for which the data can be accessed through operator[][].
