Functions | |
| const char * | version () |
| Returns the version of the fgt library as a string. | |
| bool | with_openmp () |
| Returns true if the library was compiled with OpenMP support. | |
| Vector | direct (const MatrixRef source, const MatrixRef target, double bandwidth) |
| Computes the direct Gauss transform with equal weights. | |
| Vector | direct (const MatrixRef source, const MatrixRef target, double bandwidth, const VectorRef weights) |
| Computes the direct Gauss transform with provided weights. | |
| Vector | direct_tree (const MatrixRef source, const MatrixRef target, double bandwidth, double epsilon) |
| Computes the direct Gauss transform using a kd-tree. | |
| Vector | direct_tree (const MatrixRef source, const MatrixRef target, double bandwidth, double epsilon, const VectorRef weights) |
| Computes the direct Gauss transform using a kd-tree and weights. | |
| Vector | ifgt (const MatrixRef source, const MatrixRef target, double bandwidth, double epsilon) |
| Computes the Improved Fast Gauss Transform. | |
| Vector | ifgt (const MatrixRef source, const MatrixRef target, double bandwidth, double epsilon, const VectorRef weights) |

Top-level namespace for all things fgt.
| typedef Eigen::Ref<const Matrix> fgt::MatrixRef |
Convenience typedef for a reference to our type of Eigen::Matrix.
We accept references to our functions in case the argument isn't exactly a Eigen::Matrix, for whatever reason.
