sparsesvd 0.2-2 (2023-01-14)

change unsafe sprintf() to snprintf() as demanded by CRAN (though entirely unjustified, as DRH would tell them in no uncertain terms)
omit SVDLIBC file I/O functionality (where sprintf() occurred) entirely as it is not needed by R wrapper

adapted to avoid deprecated format conversions in Matrix v1.4-2
sparsesvd() now supports wider range of Matrix input formats, but requires Matrix >= 1.3
fix incorrect gender of package maintainer

this release fixes several bugs in the underlying 3rd-party SVDLIBC code, which produce incorrect results or get stuck in infinite loops for highly sparse matrices that require multiple restarts of the Lanczos iteration; various corner cases including small diagonal matrices were also affected
a faulty RNG implementation in SVDLIBC contributed to triggering these bugs (but was not the root cause); the RNG has also been fixed
original bug report from Abdelmoneim Desouki <[email protected]>

for some inexplicable reason, R on Oracle Solaris 10 (i386) doesn't like C functions named "store", leading to a segmentation fault and test failures on CRAN
function store() has been renamed store_vec() in the 3rd-party C code included in the package
