Excellent; exactly what I was looking for.
Now, there are opportunities for a rant here:
1. This forum is actually kind-of hard to use. What is a good way to scan quickly through previous threads? Seems like old stuff just disappears (and no, the search box does not cut it).
2. To my technical problem; it seems that the specific task I was having difficulty with is not particularly rare. I coud not find >any< hint to the solution in the Maple docs neither under plot & friends nor under matrix & friends. Am >I< just stupid, or are the Maple docs...?
Anyway, don't really need to answer these, but if Maple employees look at this forum maybe they can take this as feedback.
