k1exponential: 1D Exponential Kernel Matrix for '"lineqGP"' Models.

In lineqGPR: Gaussian Process Regression Models with Linear Inequality Constraints

Description

Compute the 1D Exponential kernel for "lineqGP" models. attr: "gradient".

Usage

k1exponential(x1, x2, par, d = 1)

Arguments

x1	a vector with the first input locations.
x2	a vector with the second input locations.
par	the values of the kernel parameters (variance, lengthscale).
d	a number corresponding to the dimension of the input space.

Value

Kernel matrix K(x1,x2) (or K(x1,x1) if x2 is not defined).

Examples

x <- seq(0, 1, 0.01)
K <- k1exponential(x, x, par =  c(1, 0.1))
image(K, main = "covariance matrix using a Exponential kernel")
