Detailed Description

template<typename TKernel>
class DualtreeVKde< TKernel >

A computation class for dual-tree based variable-bandwidth kernel density estimation.

This class builds trees for input query and reference sets on Init. The KDE computation is then performed by calling Compute.

This class is only intended to compute once per instantiation.

Example use:

    DualtreeVKde fast_kde;
    struct datanode* kde_module;
    Vector results;

    kde_module = fx_submodule(NULL, "kde", "kde_module");
    fast_kde.Init(queries, references, queries_equal_references,
                  kde_module);

    // important to make sure that you don't call Init on results!
    fast_kde.Compute(&results);
