noise

add_noise

This function adds Gaussian noise to coordinate data contained
in a matrix. It is called by samplers to introduce noise when <code>sd</code> is
passed a positive value.

Uniform random samples from simple manifolds, sometimes with noise,
are commonly used to test topological data analytic (TDA) tools.
This package includes samplers powered by two techniques: analytic
volume-preserving parameterizations, as employed by Arvo (1995)
<doi:10.1145/218380.218500>, and rejection sampling, as employed by
Diaconis, Holmes, and Shahshahani (2013) <doi:10.1214/12-IMSCOLL1006>.
