Description: GNU R solvers for large-scale eigenvalue and SVD problems
 This package provides a R interface to the 'Spectra' library
 <https://spectralib.org/> for large-scale eigenvalue and SVD
 problems. It is typically used to compute a few
 eigenvalues/vectors of an n by n matrix, e.g., the k largest eigenvalues,
 which is usually more efficient than eigen() if k << n. This package
 provides the 'eigs()' function that does the similar job as in 'Matlab',
 'Octave', 'Python SciPy' and 'Julia'. It also provides the 'svds()' function
 to calculate the largest k singular values and corresponding
 singular vectors of a real matrix. The matrix to be computed on can be
 dense, sparse, or in the form of an operator defined by the user.
