I have got a discrete power law distribution from which I would like to sample.
I tried to define a new distribution, but didn't succeed so far.
The probability p(k) = C(gamma)*k^(-gamma),

With ProbabilityTable I've got the problem that my distribution is not limited to a certain range. It starts from a lower limit kmin, but goes to infinity.

Why does the evalb function return 'false' for the following function test?


This function should return true, but does not.  Any comments/corrections would be appreciated.  Thank you for your help.


I am able to get the matrices entered and they are assigned line numbers in the worksheet.  I am trying to add two matrices and having no luck.  I have tried (1)+(2)  [those are the line numbers assigned by Maple] but I am only getting an answer of 3 for the line numbered (3).

I hope I am making sense.   Perhaps as I think it through, I am not entering the matrices correctly?  I am using the matrix maker on the left side.  If anyone has any help I would really appreciate it.

I'm new to here and new to maple and I've got 3 questions:

1. Is it possible to make maple multiply two series with the cauchy product?

2. How to prove identity of two equations? Sometimes I have to differentiate a function and want to prove it with maple ... But when I differentiate with maple with diff(f(x),x) it's displayed in another way. Is it now possible to prove wether the two eqautions (mine and the one from maple) are the same, just in another notation?

A while ago, I tried to understand the dynamics of a tricky 3-D system. Back then I received great help from Robert Israel and Doug Meade. After leaving the problem aside for a while, I'm giving it another shot.

My professor wants us to verify the following

(p \/ q) V r = p V (q \/ r)

using the following Maple equivalent statement


Equivalent(a &and (a &or b),a);


The issue I have is I really do not know that the statement is asking for and where it would go. 

Thanks in advance for any help.

Int(exp(-1/100+1/1000*I*u)/(4*u^2+1)*exp(1/2*I*u),u = 0 .. 1)

The integrand has positive real and imaginary parts over the
range (just use plot it) and numerical evaluation gives it as
0.53434219089626 + 0.98249392969436e-1 * I (using Digits:=14).

A symbolic integration and using evalf gives the same.

Now writes this as

  tstData:=[a=0, b=1, m=1/2, b0 = -1/100, b1 = 1/1000];

  J:=Int(exp(b0+b1*u*I)/(4*u^2+1)*exp(u*m*I),u = a .. b);

I'm student from Malaysia.

I prefer to study about prime factorization.

Can I know the two latest prime factorization algorithm which are widely use?

Can anyone tell me how to work out correlation coefficients!!! I need it in very simple terms as I just dont get it ie if 2 variables has a correlation coefficient of .690 what does it mean?  Can someone explain it to me?  With thanks

I want to plot in 3D line segment (with 2 point) intersecting triangle(3 d with 3 points).

need help


I am a french student and I want to now if maple can transform a picture to a matrix.
thank you 

Gaussian Copula...

January 10 2009 marc005 3048

Does anyone know how to step-by-step set up a Gaussian Copula in Maple? 

I know how to simulate cross correlated random variables by using the Cholesky Decomposition but the requirement that the

correlation matrix must be positive define (all eigenvalues +) is such a pain! 

I know that copulas can easily be estimated in MATLAB but I have not seen one in Maple. Any ideas?
