%description
A generalization of principal component analysis for integrative analysis.
The method finds principal components that describe single matrices or
that are common to several matrices. The solutions are sparse. Rank of
solutions is automatically selected using cross validation. The method is
described in Kallus et al. (2019) <arXiv:1911.04927>.
