How do I define a distribution with an arbitrary mass function so it can be used exactly like those predifined, e.g., Statistics:-Mean(Poisson(lambda), Statistics:-MGF(Poisson(lambda),t), etc? As an example, Rademacher distribution can be used, or its straighforward generalization with probability of +1 being equal to p and that of -1 equal to 1-p=q. Thanks.

hi all...i want to write a procedure just to execute a set of maple commands without any input args e.g do some calc and plot series of graphs..i am facing 2 problems

1.inside procedure all lines are not  displayd only last line of command inside the proc is diplayed after execution

2.im choosing a proc to exec a series of commands because i can use the debugger to debug the set of codes else i cannot.

I would like to change the way arrows looking Maple under fieldplot3d. Particularly I would like them to have a rounded head and a simple stick for the base of the arrow. Anyone know how to do this? I have seen it done before, just not sure how to implement the code to do it. Thanks in advance!

I'm using maple to optimize a certain problem. I have two matrices, A and B both of size m by n. Now I want to maximize alpha(a scalar) such that Bx>=alpha*Ax for arbitrary x. So I gave maple the following problem: input:=evalm(A&*X): > output:=evalm(B&*X): > for i from 1 to m do > constraint[i]:=output[i]-alpha*input[i]>=0; > od: > Constraints:=seq(constraint[i],i=1..m); > sumconstraint:=add(x[i],i=1..n)>=10; oplos:=NLPSolve(alpha,{Constraints,somconstraint},maximize=true,assume=nonnegative); My problem is that maple sometimes can't come up with an answer and tells me:

Given "(x + y/z)" as input, how do I get the same expression in the form of "(xz+ y)/z". I need to make this conversion, so that I can discard  the denominator and use the numerator "xz +y" as a monomial in Groebner Basis.

Does Maplesoft has an online version of Maple's user manuals? I know there are pdf versions. Thanks!

Hi:

I will really appreciate it if I can get some help with evaluating 2500(1+ r/4)^(4*5) with r taking multiples values such as 6, 10 etc.

So far I am aware of the basic eval command... eval(2500(1+r/4)^(4*5),r=6). What I want to do is evaluate this expression for multiple values of r. Thanks in advance!!

I'm trying to graph nonlinear systems of inequalities.  INEQUAL works only with linear systems.  Someone in this forum suggested IMPLICITPLOT with the option FILLED = TRUE, but this doesn't always give the desired results since that option only gives the area between the curve and the x-axis a solid color.  What I need is the power of OPTIONSFEASIBLE, OPTIONSEXCLUDED, OPTIONSOPEN, and OPTIONSCLOSED (options available with INEQUAL) that will work with nonlinear inequalities.

Hello,

I use Maple 11 and I created a procedure (call it MyProcedure), which ends

> display([seq(r||Index, Index=1..NumberOfIterations)],insequence=true);

Futhermore I have a maplet with

> Plotter['PL1']()

and

> Button['BT1']("Draw", width=90, onclick=Evaluate('PL1'=MyProcedure(.....)))

This works ok. Result is displayed in the plotter. However I would like to add other buttons, which will work with this animation. I mean to use functions like Play, Stop, Next Frame, etc. How can I do this?

Very often I have to insert map(assume,[k,lambda,L,...many others...],real) in order to simplify my expressions.

As a simple example, compare Re(exp(I*k*x)) assuming k::real,x::real; to the result without assuming.

So I'd like a procedure/command that makes Maple assume that every symbol in an expression is real but not the expression itself.

<p>hi,</p>
<p>i tried to write a maple procedure that creates a prefix free tree based on the algorithmen of Shannon-Fano. the theory how the algorithm works is easy but for translating that into a maple procedure causes me headaches.</p>
<p>right now im stuck in the part where i have to split the characters i got until i only have one left. i suppose until that point my procedure might be ok but i how do i continue now? i lack the maple know-how to get further now....and i suppose i did already things wrong because i don't know how to save my nodes</p>

Hello, I'm trying to find a function f(r,r') such that G(r,r')=1/(r-r')+f(r,r'), where r=sqrt((x-x')^2+(y-y')^2+(z-z')^2). I have 6 boundary conditions of the form: G(x,y,a)=0, G(x,y,-a),=0, G(b,y,z)=0, G(-b,y,z)=0, G(x,c,z)=0, G(x,d,z)=0 where a,b,c,d are known constants. How do I do that in maple? Thanks
