kmatrixGauss: Gaussian Kernel Computation (Particularly used in Kernel Local Fisher Discriminant Analysis)

Description

Gaussian kernel computation for klfda, which maps the original data space to non-linear and higher dimensions.

Usage

kmatrixGauss(x, sigma = 1)

Arguments

Value

K n x n kernel matrix. n is the number of samples.
