%description
Set of functions for sparse matrix algebra. Differences with other sparse
matrix packages are: (1) we only support (essentially) one sparse matrix
format, (2) based on transparent and simple structure(s), (3) tailored for
MCMC calculations within G(M)RF. (4) and it is fast and scalable (with the
extension package spam64). Documentation about 'spam' is provided by
vignettes included in this package, see also Furrer and Sain (2010)
<doi:10.18637/jss.v036.i10>; see 'citation("spam")' for details.
