r-cran-rspectra

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.

libctl7

library for flexible control files

libctl is a free Guile-based library implementing flexible control files for scientific simulations. It was written to support the MIT Photonic-Bands program, but will hopefully prove useful in other programs too.

libteckit0

Encoding conversion library

TECkit is a toolkit for encoding conversions. It offers a simple format for describing the mapping between legacy 8-bit encodings and Unicode, and a set of utilities based on such descriptions for converting text between 8-bit and Unicode encodings.
