Each patch gives an equal share of a portion of its value to its neighbor patches.

WorldMatrix or worldArray object.
Character. If the
Numeric. Value between 0 and 1 representing the portion of the patches values to be diffused among the neighbors.
Integer: 4 or 8. Represents the number of neighbor patches considered.
Logical to determine if the
WorldMatrix or worldArray object with patches values updated.
What is given is lost for the patches.
torus = TRUE, all patches have
nNeighbors patches around
some may be on the other sides of the
torus = FALSE,
patches located on the edges of the
world have less than
nNeighbors patches around them.
However, each neighbor still gets 1/4 or 1/8 of the shared amount
and the diffusing
patch keeps the leftover.
