In OSFD: Output Space-Filling Design

(Quasi) uniform points in a p-dimensional ball

Description

ball_unif generates random or quasi-random uniform points in a p-dimensional ball.

Usage

ball_unif(cen, rad, n, rand = TRUE)

Arguments

cen	a vector specifying the center of the ball.
rad	radius of the ball.
n	number of points.
rand	whether to generate random or quasi random points. The default value is TRUE.

Details

ball_unif generates random uniform points or quasi uniform points by twinning algorithm in a p-dimensional ball.

Value

a matrix of the generated points.
