Description

This function generates the directions u for which the geometric quantiles are computed.

Usage

1
ball_2d(r, n = 10)

Arguments

r

length of u computed as √{u_1^2+u_2^2}.

n

number of u's, default is 10.

Details

The Eulicdean norm of u has to be ≤ 1, see Chakraborty, B. (2001).

Value

a matrix of dimension (n,2) containing rowwise the distrinct u's.
