Input
- d --> data dimensionality.
- N --> number of source points.
- M --> number of target points.
- X --> d x N matrix of N source points in d dimensions.
- h --> source bandwidth or scale.
- q --> 1 x N vector of the source strengths.
- Y --> d x M matrix of M target points in d dimensions.
- epsil --> desired error
Ouput
- G --> 1 x M vector of the Gauss Transform evaluated at each target point.
