Evaluate.Kernel: Evaluate Kernel

Description

This function computes the kernel (correlation) matrix. Given the kernel class object and the input data \(X\) of size n, this function computes the corresponding \(n\times n\) kernel (correlation) matrix.

Usage

Evaluate.Kernel(kernel, X)

Value

a kernel class object

X

input data
