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

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[][]
.
