Sampling on the Sphere — sphere • rgudhi

The function sphere() enables uniform sampling of random i.i.d. points on a \((d-1)\)-sphere in \(R^d\). The user should provide the number of points n_samples to be generated on the sphere and the ambient dimension ambient_dim. The radius of the sphere is optional and is equal to 1 by default. Only random points generation is currently available.

Usage

sphere(n_samples, ambient_dim, radius = 1)

Arguments

n_samples: An integer value specifying the sample size.
ambient_dim: An integer value specifying the dimension of the ambient space.
radius: A numeric value specifying the radius of the sphere. Defaults to 1.0.

Value

A numeric array of shape \(n_\mathrm{samples} \times \mathrm{ambient\_dim}\) storing n_samples points uniformly sampled on the sphere of dimension ambient_dim - 1.

Examples

if (FALSE) { # reticulate::py_module_available("gudhi")
sphere(10, 2)
}
