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.
Remark: This package is maintained by Debian R Packages Maintainers at

This package is a predependency for my final target r-other-uwot.
