Where Maple is statistics compared...

Good Morning.

I would like to know where Maple is statistics compared with other software. As a justification for the thesis i am doing. I found a page http://www.scientificweb.com/ncrunch/, but a report in 2008. I wish something more recent.

Thanks

fourier coefficients...

HI,

I am trying to solve for fourier coefficients but can't figure out the error in the code. Need help to debug the code.

Also if possible how to find the harmonics in the curve defined in the code.

following is the website from where i got this code

HI,

I am struggling with simple multiplication shown in the attached file:

Is there any specific multiplication command I should use.

Pls guide me in respect of how to make plot after multiplying A and B

How I can write a set of nonlinear coupled ODEs in...

I have a set of nonlinear and coupled PDEs for a cable actuated system. I want to transfer this set to a set of ODEs and write it down in Matrix form. I used Galerkin's method and derived the ODEs in discritized form. I have a problem in converting this set of equation into a matrix form like "Mq"+Cq'+Kq=F". The derived equations are very complicated and contains some nonlinear terms. One of the three equations looks like this:

I have a problem.

I solved a problem, but i like to get one solution for one variable.

i send my project.

Code explanation...

Hi Dr. Kamel Boughrara,

I have a question,  I know phi = B*A, but in code i can't understand a part of it, can you kindly explain it in engineering terms.

kindly see the attach file for phi.

Second question

why e-->sum(factor(e(t)),n=1..100), wht this means,

Programing relation to solution...

Hi Dr. Kamel Boughrara,

I have question regrding the analytical solution in section 3.3,  I am attaching a file.   Question is regarding  the programming you did, does it has any effect on the solution.  Because i tried to change the values for p, and other variables but could't see the effect.

Also wht the following variable means;

Good morning.

I want to do a program in a worksheet that it can recall other workeet for plotting with display.

I don´t know how can recall other worksheets.

connot run the loop...

Hi
I wrote a loop which is too long but I need its continuity so I wrote all of them in one loop.
The problem is too much time is needed to run it,even maple cannot run it.
I do not know whether my software has a problem or the way I wrote the program is wrong.
I attached the file.
thanks

how to define a correct Commutator relations with ...

Hi, friends

The physics package was provided a good tool to compute Commutator or anticommutator relations. Here, I met some problems.

Example 1:

restart: with(Physics):Setup(mathematicanotaion=true):

Setup (op={p[x],p[y]},p[z]):

alg:=%commutator(p[z],p[x])=2p[x], %commutator(p[z],p[y])=-2p[y], %commutator(p[x],p[y])= p[z]
