rbfKernDiagGradX: Gradient of RBF kernel's diagonal with respect to X.

In alkalait/gptk: Gaussian Processes Tool-Kit

Description

computes the gradient of the diagonal of the radial basis function kernel matrix with respect to the elements of the design matrix given in X.

Usage

rbfKernDiagGradX(kern, X)

Arguments

kern	the kernel structure for which gradients are being computed.
X	the input data in the form of a design matrix.

Value

gX	the gradients of the diagonal with respect to each element of X. The returned matrix has the same dimensions as X.
