Kernel: The 'Kernel' class object

Description

This a abstract class provide the kernel function and the 1st order derivative of rbf kernel function.

Value

an R6Class object which can be used for the rkhs interpolation.

Format

R6Class object.

Methods

kern(t1,t2)

This method is used to calculate the kernel function given two one dimensional real inputs.

dkd_kpar(t1,t2)

This method is used to calculate the gradient of kernel function against the kernel hyper parameters given two one dimensional real inputs.

dkdt(t1,t2)

This method is used to calculate the 1st order derivative of kernel function given two one dimensional real inputs.
