Does anybody know whether there's a library with which I can efficiently compute Minkowski-Sums of Polytopes or Polyhedra?

I want to load C++ code into Maple12. Is that possible?

In which format do I need the files (.obj, .exe or just .cpp)?

Thanks!

Hi, I have the next problem:

I have the equation z:=x+y*i, and i have to animate the equation z^3-z+A. I have to animate by the parameter A from -2 to 2. How can i put animate and complexplot together?

thanks a lot =)

So I am doing some algebra calculations with what I thought were Lie Algebras.   It looks like

Hello everyone, I was wondering if I can get some advice on solving two integral equations given below for u and b. y(r) is parametrically dependent on 'u' and 'b'. l := -C1*(int((3*polylog(5/2, -exp(b*(u-y(r))))/b^(5/2)+y(r)*polylog(3/2, -exp(b*(u-y(r))))/b^(3/2))*r^2, r = 0 .. 10.))-C2=0; I2:=C3*(int(r^2*polylog(3/2, -exp(b*(u-i))), r = 0 .. 10.))/b^(3/2)-1=0; where C1,C2,C3 are numbers and y(r) is parametrically dependent on 'u' and 'b'.

 

I have a button and a math container where the button code is given below.

The code simple generate 4 random numbers when you press the button and save the random numbers in a list which

is displayed in the math container.

 

with(DocumentTools):
with(Statistics):

to 4 do

r:=evalf(Sample(RandomVariable(Normal(0,1)),1)[1],1);

if not assigned(LL) then LL:=[r] else LL:=[op(LL),r] end if;

end do;

Do(%MathContainer3=LL);
 

 

How do I number the pages in a Maple worksheet?

I try to fit curve through set of points that I read  from a graph. Then use equation of this curve to define a function function. Only bspline approximation gave acceptable result. But how can I use it in defining a function?

 

XvalsCf := [0, 5, 10, 25, 50, 100, 140, 200, 250, 300, 400]

valsCf := [0.5e-2, 0.4e-2, 0.3e-2, 0.26e-2, 0.23e-2, 0.21e-2, 0.2e-2, 0.19e-2, 0.18e-2, 0.175e-2, 0.15e-2]

 

Another issue is in "surface fitting". Graph shows propeller efficiency curves. I'd like to get equation of surface spread on those curves.  Axis x is an angle, axis y V/nD and z is efficiency.

Again using spline/bspline approximation is nesssary to get accurate results.

I will use this efficiecny surface function equation in drive optimization .

 

Is creation of such surface/function  possible in maple.

 

Thank you in addvance for your help.

I recently optimized a fairly large function with 100+ parameters using the Minimize command. In order to keep track of everything, I gave them logical names (ie. qk0, qk1...). Instead of preserving the order in the output, maple reported the solution as a set and not a list. Can I change this. I know that with minimize (lower-case) I can set location=true. Any ideas for Minimize? Also, what about exporting the results to Excel/Numbers for analysis? All help is greatly appreciated. Steve

I have a function of two variables, f(x,y).
The function does involve in infinite series of functions fn(x,y)

   f(x,y) = sum( fn(x,y) ,  n=-100..100)

but that shouldn't be an issue.

I need to solve numerically the roots of f, obtaining a stored function y(x) over a range x=0..1/2.

Finally, I take y(x) and evaluate another function, g[ x, y(x) ]  over the range of x.
g(x) would be plotted.

here i have an ode system:

diff(x(t),t)=f(x,y,z,w); diff(y(t),t)=g(x,y,z,w);diff(z(t),t)=h(x,y,z,w); diff(w(t),t)=k(x,y,z,w) where f, g, h, k are given nonlinear functions.

Then how can i get the phaseplan of (x(t),y(t))? when i use the procedure of DEplot, it returns an error stating that the DESYS requires two or fewer variables? how can i deal with that?

Any help will be greatly appreciated!

 

I try to put a prefix in front of the Omega unit (ohm). I does not work (see the attached file). The same kind of prefix works for all the other units.   Thanks

Hi everybody, I have the following problem: If I denote by : He:=(n,k,x)->(-1)^n*(n!)^(1/2)* (GAMMA(n+k+(1/2)))^(-1/2)* LaguerreL(n,k-(1/2),x^2); and Ho:=(n,k,x)->(-1)^n*(n!)^(1/2)* (GAMMA(n+k+(3/2)))^(-1/2)*x* LaguerreL(n,k+(1/2),x^2); Can I compute the series: sum(He(n,k,x)+Ho(n,k,x),n=0..infinity); Using Maple. Thanks

Hello all, I am still quite new to Maple and this website, and apologize if this is an easy task or one that has been already addressed on the forums. I am trying to calculate an adiabatic invariant for a particle orbit. This invariant is the action over one oscillation in the particle's trajectory, and requires me to numerically integrate aspects of the plot in phase space. I calculated and plotted the particle's trajectory in phase space using the dsolve and odeplot commands. The invariant is given by the expression \int_{1 cycle} rho' drho

If a student enters/chooses an incorrect answer, can negative marks be given?
