Hi,

I've been having problems trying to get Maple to multiply matrices together inside of a for loop (well, 3 actually).  In fact it sometimes has the same problem outside of the list, but not always.  I've included the file below: it's a cut down version of the normal page, but it gives the same error.  Note that Maple is fine for multiplying matrices together in the first few cases (defining M, M2, N1, N2), but it breaks down on L - despite the fact that it can do the very same calculation at the bottom of the page without problem.

Hi,

I was wondering if anyone could tell me whether (and if so, how) it's possible to get Maple code to run an external program mid-process?  The program in question is qHull, which I downloaded from www.qhull.org.  Some searching has informed me it's possible to run C and JAVA bits in Maple, but with no programming experience I'm not sure whether that extends in any way to this, or if so, how.

Hi,

I'm new here and was wondering if anyone could offer me some advice on some work I'm doing.  I've written some code in Maple to generate images of fundamental domains in Hyperbolic 3-space, but in order to get the necessary results, I have to do some convex hull calculations.  Currently I'm using qHull for this, which works well, but outputs its results in the form of a text file, reading in the following format:
