MaplePrimes Questions

I've been exploring the link between Maple and Matlab, and there seems to be no documentation on how to use Maple to call commands (or .m files) in Matlab. On the other hand, it doesn't state that this is not possible. Has anyone else looked into this?
I am trying to create a procedure like this: myproc := proc(x) Digits := x; sqrt(x) end proc; and then I want to plot the results like this: plot(myproc(x), x=2..20); However, I get an error: "Invalid assignment to Digits". The following works fine, however: seq(myproc(x), x=2..20); How can I solve this? Thanks.
How do I get maple to do polynomial long division?
It's obvious how to use Maple 10 for creating a document, but has anyone used Maple 10 for presentations? I'm going to present in a seminar in a couple of weeks and have some Maple demonstrations and graphics to show the group. I'd be interested in hearing tips, suggestions, experiences and ideas for presenting mathematical content to a group from within Maple. (I'm familair of course, with Powerpoint and LaTeX slides, and the LaTeX Prosper package. I'd use LaTeX/Prosper except that then I have to embed the Maple in the presentation. It would be more convenient if I can use Maple solely.)
Dear All, First of all thank alec and Prof Doug. Please refer to post My problem is to solve the following ODE with constrain given by the Eq: > DEq := diff(f(x),x) = c1*sqrt( g(f(x)) - g(f(x=x1)) ); > Eq := ug - f(x=0) = c2*sqrt( g(f(x=0)) - g(f(x=x1)) ); > g(f(x)) := exp(f(x)-xn) +exp(-f(x)) +(1-exp(-xn))*f(x); where ug is the independent variable and others are parameters > c1 :=-257753830.552993398770016153893; > c2 :=1.40376701562707174099362643812; > xn := 35.4196679725860384893589519100; > x0 := 0; > ug := 40; I have tried to followed alec's suggestion but the solution sometime still cannot be obtained. The independent variable ug has to be varied from -50 or less to + 100 or more. The intial guess in solving f0 (f0 := fsolve(g('fx0'(f0))-gfx0(f0),f0=30);) has to be input manually, this is a big drawback.

In the third line of this do loop is the assignment assigning both the null set and the new value of the index into the original null set ? Also does this mean that the final set S contain the original null set with multiple null sets nested in it ? >
What does "Warning, `delta_Ia_con_p` is implicitly declared local to procedure `inductor_current_RMS_AVG_p`" exactly mean?

I get this, when I execute the following procedure:

# art=0 returns RMS current and art=1 returns AVG current
> inductor_current_RMS_AVG_p:=proc(Ue,Ua,Ia,L,T,art)
> delta_Ia_con_p:=(Ue-Ua)/L*Ua/Ue*T;
> inititial_inductor_current_con_p:=Ia-delta_Ia_con_p/2;
> initial_inductor_current_p:=piecewise(Ia<eval(IaLG_boundary_condition), 0, inititial_inductor_current_con_p);
> # initial_inductor_current_input:=initial_inductor_current;
> inductor_current_increase_p:=initial_inductor_current_p+(Ue-Ua)/L*t;
i put system of eqn to dsolve (3) sol := dsolve([sysode, icsode]); and i am getting sol:= is it means that maple can't solve it?
i have a function f(q(t),...)= q(t)*sin(q(t)). i need to do df/dq(t). how? thank's
how do i count the numbers of elements inside of a list like [[x,y,z]]? ie. [[3,2,5],[2,34,6]]. i would want it to return 2.
Why do I get the same output with the two following statements plot3d(0, 0..20, 0..70, color=proc(x,y) 200000*x end proc); plot3d(0, 0..20, 0..70, color=proc(x,y) x end proc); How does the option "color=proc() ..end;" works? How can I choose the colors? (The reason behind my question is that I am trying understand how to plot the Mandelbrot set)
i have a list in the form of [[x,y,z]] where x,y,z are integers, i want to find all the elements of the form [0,y,z]. how do i do that?
This is a screenshot of what I get when I open Maple 10 (copy and paste url) The Maple Calculator also results in the same problem What Java programs are required for Maple 10? I have the Microsoft Virtual Machine installed as well as Microsoft SDK 4.0. I am running XP with SP2. Any help is greatly appreciated.
Why am I getting a false statement as output for this input ? > >
