## key bindings and acceptance of automatic key press...

Hi Everyone:

As far as I know maple has no way to define key bindings for it's actions.

I would however like to be able to navigate around the worksheet using hjkl keys - namely alt+j would be equivalent to down_arrow, and so on. I find that I spend more time reaching for the arrow keys or the mouse than writing useful code (I might be exaggerating slightly here ;) ). I can implement this behavior easily using my window manager (FVWM) - meaning the window...

## Multibarrier Problem - Schroedinger...

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:

> 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

## System of quasilinear PDEs...

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...

## Brownian Motion_Mean not zero...

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).

## How do I set repeat count for a format descriptor ...

Hi all!

Please I'm having difficulties in specifying a repeat count for my format descriptor in Maple. For example,
If I want to repeat the format descriptor "%-+8.4f" ten times, is it compulsary that I write it explicitly as shown below?

fprintf(file, "\n%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f%-+8.4f",e[5],mp[5],zp[5],mt[5],zt[5],roc[5],ac[5],pnloc[5],fs[5],qcode[5]):

## How to differentiate between expanded and factoriz...

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');
