Package ‘Matrix’ June 1, 2021 Version 1.3-4 Date 2021-05-24 Priority recommended Title Sparse and Dense Matrix Classes and Methods Contact Doug and Martin <[email protected]> Maintainer Martin Maechler <mmaechler+[email protected]> Description A rich hierarchy of matrix classes, including triangular, symmetric, and diagonal matrices, both dense and sparse and with pattern, logical and numeric entries. Numerous methods for and operations on these matrices, using 'LAPACK' and 'SuiteSparse' libraries.
