Package topo :: Package pattern

Package pattern

Objects capable of generating a two-dimensional array of values.

Such patterns can be used as input to a Sheet, as initial or fixed weight patterns, or for any other purpose where a two-dimensional pattern may be needed. Any new PatternGenerator classes added to this directory will automatically become available for any model.
