%description
Implements finite mixtures of matrix-variate contaminated normal
distributions via expectation conditional-maximization algorithm for
model-based clustering, as described in Tomarchio et al.(2020)
<arXiv:2005.03861>. One key advantage of this model is the ability to
automatically detect potential outlying matrices by computing their a
posteriori probability of being typical or atypical points. Finite
mixtures of matrix-variate t and matrix-variate normal distributions are
also implemented by using expectation-maximization algorithms.
