Having overcome a Java VM problem, I have a further problem which is now
limiting my use of MAPLE 14 on Vista:  plotting is limited to plots with
relatively few points or graphical content.

Here is an example in MAPLE 14 (in classic and the normal modes):

> with(RandomTools):with(Statistics):
> N:=400;
> rlist:=(Generate(list(float(range=-1..1),N))):
> plot(rlist,color=black,thickness=1);

This works fine up to N=170,...

Would much value shared experience or solutions on this

Thanks

Hi I am in the process of solving 4 coupled PDEs, with their associated ICs and BCs and have obtained solutions up to a time t=T, but at this time I need to change one of the boundary conditions on one of the dependent variables from a value condition to a gradient condition. 1) Can this (structural) change in the BCs at t=T be built into the set of BCs set right at the start of the running the solution, and if so how?
