ToyNoise2 {cope}

Generate a realization of the Toy Noise 2.

Description

Generate a realization of the Toy Noise 2.

Usage

ToyNoise2(n = 1, Ns = 64, model = list(), theta = 0.1, l1 = 1,
  l2 = 4, tau = 40)

Arguments

n

The number of realizations to produce.

Ns

Number of pixels of the result in one direction. The resulting picture will have Ns x Ns pixels.

model

The correlation structure of the noise, as used by arima.sim. Default is list() which gives i.i.d. noise.

theta

Bandwidth of kernel used to smooth the noise.

l1, l2

Pixel size of the noise blocks in either side of the domain. See main reference for details.

tau

Scaling factor with which noise is multiplied after generation.

Value

A list containing x and y, the coordinates of the grid and z and array of dimensions c(64,64,n) giving n reallizations of the Toy Noise 2.
