%description
R interface to 'PRIMME' <https://www.cs.wm.edu/~andreas/software/>, a C
library for computing a few eigenvalues and their corresponding
eigenvectors of a real symmetric or complex Hermitian matrix, or
generalized Hermitian eigenproblem.  It can also compute singular values
and vectors of a square or rectangular matrix. 'PRIMME' finds largest,
smallest, or interior singular/eigenvalues and can use preconditioning to
accelerate convergence. General description of the methods are provided in
the papers Stathopoulos (2010, <doi:10.1145/1731022.1731031>) and Wu
(2017, <doi:10.1137/16M1082214>). See 'citation("PRIMME")' for details.
