If I remember correctly, regular matcens don't work unless told to (special matcens for example work in co-op, whereas regular ones don't). The only difference is ofcourse, a script command to say '' TURN ON, SPEW STUFF AT ONCE!''
That being said though, it's been a while since I touched Matcens and I've forgotten already! Pay attention to the D3 campaign in co-op though, take for example Level 14 - In the mirror alignment area, the little rooms below the main hall contain matcens which can be powered on and off, yet it has no affect in co-op.
