RFF: Evaluate an RFF (random wave function) at given input

In TestFunctions: Test Functions for Simulation Experiments and Evaluating Optimization and Emulation Algorithms

Evaluate an RFF (random wave function) at given input

Description

Evaluate an RFF (random wave function) at given input

Usage

RFF(x, freq, mag, dirr, offset, wave = sin, noise = 0)

Arguments

x	Matrix whose rows are points to evaluate or a vector representing a single point. In 1 dimension you must use a matrix for multiple points, not a vector.
freq	Vector of wave frequencies
mag	Vector of wave magnitudes
dirr	Matrix of wave directions
offset	Vector of wave offsets
wave	Type of wave
noise	Standard deviation of random normal noise to add

Value

Output of RFF evaluated at x

Examples

curve(RFF(matrix(x,ncol=1),3,1,1,0))
curve(RFF(matrix(x,ncol=1),3,1,1,0, noise=.1), n=1e3, type='p', pch=19)

curve(RFF(matrix(x,ncol=1),c(3,20),c(1,.1),c(1,1),c(0,0)), n=1e3)
