I have tried without sucess to run the

Equation manipulator.

I get the following error:

"

Error, (in Maplets:-Tools:-CleanElements) invalid input: op expects 1 or 2 arguments, but received 0

"

Do I have to load some package for it to run?

I have searched for a solution but can not find one.

Getting desperate.. anyone?

TIA

Hi

How  can we draw diagrams in tripartite coordinate system?

Hello,

How to Factorize the coefficients of this matrix :

> A:=Matrix([[x^3+x-2,x^2+x],[x,x+1]]);

factor(A) does not work !

Thank you,

Gérard.

I would like to ask your assistance in understanding the following Maple interaction which speaks for itself.

There is a desire to explore the process of filtration combustion. To do this, you must solve a system of differential equations in partial derivatives.
I write down all the equations.
Boundary conditions in Maple 2015.0 interpreted incorrectly.
I need to write like that:

given that:

It turns out so:

ie somewhere lost derivatives

,....

As in Maple record boundary conditions correct?

Thanking you in advance.

Hello,

Thanks to the function Exports, it is possible to see the differents functions and modules which are in a module.

For example, I find in the module GetMultibody a module called GetLGM which permits to conduct some linear graph analysis. I'm interested by this module.

However, to my knowledge, I didn't see any help on this module.

How can I do so as to understand the inputs to give to the functions of this module in order to use the functions of this module ? In other words, how it is possible to use functions from a module when you don't have any help at your disposal ? 

Thanks a lot for your help.

Hi,

Im trying to study some questions and I'm using maple to verify my answers.

Theres a few polynomial factoring questions and linear equation questions Im trying to get

maple to show its solutions steps using showsolution() no matter where I put it  the function wont work.

Ive switched between math/text functions. Im still pretty new to maple but I can't find any information on how to do it

on the web/youtube.

Thanks in advance!

into the "Ask a Question" window?

Nothing to add

Actually I want to ask something else.

I am getting the following expression when I partially differentiate an expression:

PDE11 := diff(theta(z, p), z, z, p)+2*lambda(p)*theta(z, p)*(diff(lambda(p), p))+lambda(p)^2*(diff(theta(z, p), p))+lambda(p)^2*(sin(theta(z, p))-theta(z, p))+2*p*lambda(p)*(sin(theta(z, p))-theta(z, p))*(diff(lambda(p), p))+p*lambda(p)^2*(cos(theta(z, p))*(diff(theta(z, p), p))-(diff(theta(z, p), p)))

I differentiate the above equation to get each term in the form of :table([f=......])

(table([f = 1+sum(Lambda[n](0)/factorial(n), n = 1 .. infinity)]))(p)^2

It is difficult to understand the expression. Maple does not show any error. Can you please tell me what the error is?

hi every one

please see attached file blew and help me for dsolve set equations.i dont know aboue errors with in

thanks

equation.mw

Take for instance the signal [1,0,-3,2,1,0,1,2] (considered in Wavelets for Kids, Vidakivic & Mueler, AMS, 1991).

I want to anlalyse it down to the level zero with Haar wavelets. It seems that MAPLE's commnad only applies once.

Hi !

I am trying to solve a pde with initial/boundary conditions, in the numeric mode. It works very well when I provide 3 numerical conditions : 1 initial condition (uniform distribution at first), and two boundary conditions.

Now I want to switch the initial condition to a function of r. It's a polynome I obtained after interpolation of another result. I tested it and the function interp20(r) works. But the pdsolve doesn't seem to evaluate the function, when it comes to start the procedure and pdsolve doesn't return a module as it should, although it doesn't send any message error.

You can see the code following, with the error messages I get.

Is it strictly impossible to use a function as an initial condition ?
Is it just a problem I could solve by converting the function or its result to something else ?
Is float the right type of input ? For example, if I write a:=283.15, is it a float ?
Have you already had similar problems ? How did you solve them ? Where could I find working code examples on this ?
Could I solve this problem with non-uniform initial condition with another Maple function ?

Then you very much for your help !

hi.i have problem for dsolve equation.please help me again

thanks alotequation.mw

Hi everybody.

In the following attached file, I have created 3 matrices with 13*13 and 13*6 dimensions and their components are numeric. I closed Maple and ran it again. Surprisingly, when I try to browse the matrices again, I encounter with this problem " empty RTable structure" while I imported the components, manually.

Thanks in advance for your answers.

I think that I found a bug in Maple! Please run the following command:

I need the Generators of above Ideal. What is your idea?!
