Dear all,

I am trying to simulate the penetration of the wavefunction into a potential barrier consisting of two barrier steps of different heights, V1 and V2.

My code looks like that:

> restart;
> m := 0.91e-30;h := 0.1055e-33; V1 := 10*0.16e-18; V2 := .8*V1;a := 0.10e-9;En := .6*V1; w := En/h;

Hey guys,

How do I find a max in a 3d plot? I've tried plottools[getdatat] but keep getting the error of

"Error, index must evaluate to a name when indexing a module"

Thanks!

Hello,

I am trying to solve the following system of quasilinear PDEs for dependent variables pA(z,t), pB(z,t), pC(z,t) using Maple 14:

> system:= [

.15e-3*diff(pA(z,t),t)+.83e-1*diff(pA(z,t),z)+.47e-3/(1+.11e-6*pA(z,t)+.14e-4*pB(z,t)+.73e-4*pC(z,t))^2*((1+.14e-4*pB(z,t)+.73e-4*pC(z,t))*diff(pA(z,t),t)-.14e-4*pA(z,t)*diff(pB(z,t),t)-.73e-4*pA(z,t)*diff(pC(z,t),t)) = 0,

.15e-3*diff(pB(z,t),t)+.83e-1*diff(pB(z,t),z)+.90e-1/(1+.11e-6*pA(z,t)+.14e-4*pB(z,t...

Hello everyone,

I have a problem with the Brownian Motion (I'm using Maple 15).

Here is the code:

X:=BrownianMotion(0,0,1,t);

X1:=SamplePath(X(t),t=0..T,timesteps =T/d):

Mean(X1);

The last line give me a number different from zero, which is not true for a Brownian Motion as defined.

Could you please tell me where is the problem?

PS: I have the same problem with WienerProcess(sigma).

If you use all the convergents of the simple continued fraction of the MRB constant as the terms of a generalized continued fraction, then likewise use the new convergents in another generalized continued fraction, and so on... you arrive at 0.5557531....  For more on this process see https://oeis.org/wiki/Convergents_constant .

Hi,

I would be thankful if someone help me to generate primitive polynomials (of deferent degree if possible) defined over GF(2^16), i.e., the coefficients of the polynomials are in GF(2^16). Thanks in advance.

Hello!

I have to  solve following ODE set as a part of my MsC thesis

I would like download Maple 15.1. Please Help.

Hi everyone!

Please can some one show me how to implement the "system" command on Maple 13-Windows OS to include the specicfication of the input and output file path? I would appreciate a useful response. Thank you...

I have asked a similar question before but it appears that the difficulty of what I need to do increases when the cases are simpler.

Essentially I want to check that an expression has been fully simplified. Suppose that:

A:=2(a+b);

B:=2a+2b;

Is there any way to test so that

evalb(A=B) returns false?

In my case, both A and B are obtained from MathContainers:

A:=GetProperty('MathContainer1','expression');

I hope this is the right place to ask, as the links for Maple Student Help were dead. I'm trying to assign a range of values to a name in order to solve questions about binomial distribution using variations of the function shown below:

Typically, plots on a Maple worksheet fill substantial portions of the printed page when they're printed out.  What I'd like to do is resize plots, prior to printing, such that they're smaller when printed.  I'd also like all plots on a worksheet to print out at the same size.  Note that simply highlighting a plot on the Maple worksheet and then pulling the corner to resize it, is not what I want to do:  I find it very difficult to anticipate the...

Hello.

I would like to do 2D pointplot, where each x,y come from GPS reading, and each point have a colour dependent on z, where z is same measurement taken in each position ...

Basically, I have the code

solve([E1, E2, E3, E4, E5, E6, E7, E8], [C1, C2, C3, C4, C5, C6, C7, C8])

and I want to store each of the solutions (C1,C2,C3...) as a different variable.

How would I go about doing that? (without simply copy and pasting the solutions after hitting ENTER)

I thought about using

{X1,X2,X3,X4,X5,X6,X7,X8} := solve([E1, E2, E3, E4, E5, E6, E7, E8], [C1, C2, C3, C4, C5, C6, C7, C8])

but it wouldn't go through.
