The Mat in the name refers to the automatic exposure control of the shutter. In automatic mode the diaphram opening is determined by the lightmeter. An indicator in the viewfinder shows if enough light is available (green) or not enough (red). In low light situations the shutter release is blocked (only in Auto mode).
