<p>Fortunately, the initial transition matrix is sparse (it contains the
value <code>0</code> in the majority of its cells). This allows the way
it is stored in RAM to be optimized so that the amount of memory it
consumes only grows linearly with the number of cells in the landscape
data. In practice, this means the transition matrix takes up
significantly less RAM. Using a 1000x1000 landscape raster (one million
landscape cells) again as an example, the transition ma
