Description: Fits single-component and finite-mixture
    Kronecker-structured matrix-normal models and imputes incomplete
    matrix-variate data using matrix partial expectation-maximization.
    General MPEM handles arbitrary missingness, while Rect-MPEM exploits
    rectangular structural missingness. The methods are described in Lu,
    Andrews and Browne (2026) "An Efficient EM Algorithm for Both
    Element-Wise and Structural Missingness in Matrix-Variate Normal Mixture
    Models" <doi:10.48550/arXiv.2609.00616>.
