ball_unif

<code>ball_unif</code> generates random or quasi-random uniform points in a p-dimensional ball.

Methods to generate a design in the input space that sequentially fills the output space of a black-box function. The output space-filling designs are helpful in inverse design or feature-based modeling problems.
