%description
Matrix is an universal and sometimes primary object/unit in applied
mathematics and statistics. We provide a number of algorithms for selected
problems in optimization and statistical inference. For general exposition
to the topic with focus on statistical context, see the book by Banerjee
and Roy (2014, ISBN:9781420095388).
