## Buffered Output in Worksheet Mode...

I'm writing an algorithm that takes a while and I'd like to print status messages periodically. I typically use the command line interface, and this is no problem. I just do a printf whenever I need.

However, some people who will use this code prefer to use the GUI, and I've found that the GUI tends to buffer the output from printf, printing 20-30 printf statements in clumps instead of as they're called. Is there any remedy for this?

## How do I change the 2D and 3D plot scale in Maple ...

I have started to use Maple 18 and I have found that my scale starts at 2.*10^16 for all functions I graph no matter if its 3D or 2D. Is there a way to change this scale?

how to get maple to do linear algebra in Z_2 (integers modulo 2)

I don't want it to solve and then reduce mod 2 I want it to work over Z_2 so basis([ [1,1,1], [1,-1,1 ]) = [1,1,1]  etc

## How do I solve s systems of pdes in maple...

The model of fixed-bed adsorption column

Fluid phase:

PDE:= diff(U(x, tau),tau)+ psi*Theta*diff(U(x, tau),x)-(1/Pe)*psi*Theta*diff(U(x, tau),\$(x, 2))=-3*psi*xi*(U(x, tau)-Q/K);

IBC:={U(x, 0) = 0,U(0, tau) = 1+(1/Pe)*(D[1](U))(0, tau),(D[1](U))(1, tau)=0};

Particle:

PDE:= diff(Q(r, tau), tau) = diff(Q(r, tau), \$(r, 2))+(2/r)*diff(Q(r, tau),r);

IBC:={Q(r, 0) = 0,(D[1](Q))(0, tau) = 0,(1/K)*(D[1](Q))(1, tau)=xi*(U-Q(1, tau)/K)};

Pe:=0.01:

psi:=6780:

Theta:=3.0:

xi:=10000:

I will really appreciate your help. Thanks in anticipation.

## matrix computations(data-intensive algorithms) wit...

hi,

I am trying to implement some data-intensive algorithms like: comuting similarity scores, clustering etc. How efficient Maple is in doing these operations? I mean is it comparable to MATLAB in these operations? What toolboxes are useful in these? I am trying to build a recommender system.

I am using Maple18 and not sure if Maple has any advantage in implementing these type of algorithms over MATALB??

thanks

## How to use Verlet algorithm to derive the orbit of...

Derive the orbit of the Moon around the Earth by doing a Verlet algorith of Molecular Dynamics simulation. Use one hour for your step τ. Place the stationary Earth at the origin of the Cartesian system. For initial conditions, use the position and the speed of the Moon when it is at its apogee (furthest from Earth). Plot the orbit.
