result = gausskernel_matrix(G1 [, G2] [, GMA=float] [, NSCALE=float])
Returns array of Gaussian kernel functions for data matrices G1 and G2. G1 is an N x m array, G2 is an N x n array. Returned array is n x m. If G2 not present then returns a symmetric, positive definite Guassian kernel matrix
Parameters
- G1 in required
data matrix
- G2 in optional
data matrix
Keywords
- GMA in out optional type=float
if not given, calculated from the data: GMA=1/(2*(nscale*scale)^2) where scale = average distance between observations in the input space
- NSCALE in optional type=float
multiple of scale for GMA (default 1.0)
