%description
Performs partial principal component analysis of a large sparse matrix.
The matrix may be stored as a list of matrices to be concatenated
(implicitly) horizontally. Useful application includes cases where the
number of total nonzero entries exceed the capacity of 32 bit integers
(e.g., with large Single Nucleotide Polymorphism data).
