 of iterations, min
tolerance, etc). In the case of transition matrices generated from
raster data, direct solvers appear to generally be significantly faster,
but they require a large amount of memory in the process. In contrast,
iterative solvers appear to be slower in general (depending on the
structure of the data, they might be faster in rare situations), but are
substantially more memory efficient.</p>
<p>Prior to version 3.0.0, the samc package always used a direct solver.
As of version 3.0.0, the di
