A matrix can be thought of as a grib landscape with individual tiles that can be textured, raised and lowered to create a wide variety of surfaces.
One way you use matrices is to make the land for an outdoor game.
A lot of people make their own matrix editor to mold your matrix by clicking or setting an area height. Of course, there are also some other great editors out there. One being the infamous MatEDIT, which you make your matrix and texture it, then it writes the DB code FOR YOU
