(forlack of a better descriptor)...
I'm working on a problem which yields a result of the form
[ [-203 -120]]
45 -20
I can't quite draw it correctly here, but if double-click and copy from
within wxMaxima, it yields the following
[matrix([-203,-120],[45,-20])]
I need to be able to invert the matrix, but can't figure out how to get
the matrix 'out of' the first set of brackets (sorry, can't quite figure
out the appropriate vernacular here...). The preceding construct looks
like a matrix (2x2) within the single element of an outer (1x1) matrix.
Can anyone point out the obvious?
Cheers...
