Anecdote:
My EE prof used Excel to invert a matrix. Took about 30 minutes, and
was far from obvious (I forgot how it was done, since it was
definitely something Excel wasn't designed to do), when a specialized
tool (Maple in this case), did the same job in one line of code,
following the mathematical notation (M_inverse := M^-1).

Would that remark still apply if Excel had - let's say - a function
MINVERSE() - a similar single line of code?

Well, interestingly, I do believe it does.

Have a look at eg
http://www.chem.mtu.edu/~tbco/cm3450/Excel_Array_Formulas.pdf

I suspect people don't realise what power Excel has, because hardly
anyone talks about it. They either talk about everyday corporate number
crunching or conventional programming lnaguages. Few people think about
taking Excel's components and mixing them together to solve
simultanaeous linear equations.

Hmm, when you post, it fragments into a new thread in my gmail. I assume
because you change the subject. I'm trying to figure out how to fix it (
http://www.google.com/support/forum/p/gmail/thread?tid=63a2a74c9f70e02d)
but
doesn't look like it will happen any time soon. Meanwhile, I'd be
appreciative if you could just make the new subject be "Re:
#{original_subject}"

(musing: I wonder how ruby-forum knows they are part of the same thread.)
