MatrixExtra: Extra Methods for Sparse Matrices
Extends sparse matrix and vector classes from the 'Matrix' package by providing:
(a) Methods and operators that work natively on CSR formats (compressed sparse row,
a.k.a. 'RsparseMatrix') such as slicing/sub-setting, assignment, rbind(),
mathematical operators for CSR and COO such as addition ("+") or sqrt(), and methods such as diag();
(b) Multi-threaded matrix multiplication and cross-product for many <sparse, dense> types,
including the 'float32' type from 'float';
(c) Coercion methods between pairs of classes which are not present in 'Matrix',
such as 'dgCMatrix' -> 'ngRMatrix', as well as convenience conversion functions;
(d) Utility functions for sparse matrices such as sorting the indices or removing
zero-valued entries;
(e) Fast transposes that work by outputting in the opposite storage format;
(f) Faster replacements for many 'Matrix' methods for all sparse types, such as
slicing and elementwise multiplication.
(g) Convenience functions for sparse objects, such as 'mapSparse' or a shorter 'show' method.
