'Cannot evaluate Boolean' problem31 Mar 2008 18:41 GMT2
I've run into a problem trying to do an integral (Maple V R4 for OS/2), and
I don't know how to get past it.  Here's an exerpt:

Maple -> C translation of solving for square root of a matrix?26 Mar 2008 07:24 GMT1
I am trying to use Maple -> C translation facility for a special use:
I need a matrix square root function in C/C++.
I only need it for 3x3 matrix, so I decide to find some hard-coded piece of
program, instead of using some numerical library, because then I have to

Characteristic Function of the Cantor Set14 Mar 2008 22:50 GMT3
While investigating the Cantor Set with Maple and trying to graph it, I came up
with what looks like the characteristic function of the Cantor Set (or at least
a recursive approximation of it):
