r.mapcalc	Raster map calculator.
r.mapcalc.simple	Calculates a new raster map from a simple r.mapcalc expression.
r.mfilter	Performs raster map matrix filter.
r.neighbors	Makes each cell category value a function of the category values assigned to the cells around it, and stores new cell values in an output raster map layer.
