In rSPDE: Rational Approximations of Fractional Stochastic Partial Differential Equations

Update parameters of spacetimeobj objects

Description

Function to change the parameters of a spacetimeobj object

Usage

## S3 method for class 'spacetimeobj'
update(object, kappa = NULL, sigma = NULL, gamma = NULL, rho = NULL, ...)

Arguments

object	Space-time object created by spacetime.operators()
kappa	kappa value to be updated.
sigma	sigma value to be updated.
gamma	gamma value to be updated.
rho	rho value to be updated.
...	currently not used.

Value

An object of type spacetimeobj with updated parameters.

Examples

s <- seq(from = 0, to = 20, length.out = 101)
t <- seq(from = 0, to = 20, length.out = 31)

op_cov <- spacetime.operators(space_loc = s, time_loc = t,
                             kappa = 5, sigma = 10, alpha = 1,
                             beta = 2, rho = 1, gamma = 0.05)
op_cov <- update(op_cov, kappa = 4, 
                             sigma = 2, gamma = 0.1)
