dsolve event handling looks like a great tool, but I can't understand how it works and it's not sufficiently popular to google my way to examples online. There are two things I'd like to do: 1) interrupt the computation once some variable leaves a certain range, 2) interrupt the computation if the solver gets stuck into an infinite loop. Both are documented in the help, but I don't understand it. Suggestions welcome, thanks!

Hi,

I have 5 docs with datas (x,y), like this one : BEF1txt

I want to put the 5 graphs side by side (parallels linears fonctions in a 3D graph). So I added the z data, z=1 in this case, and BEF2 got z=2, etc... But I am not able to make the 3D plot with the 5 linears fonction side by side.

May you help me please?

Thanks

Hi All,

I've made an array plot of 5 plot3D objects, and I would like to export the entire set of plots to a single GIF/JPEG image. Presently, I am exporting the worksheet to an html file, for convenience. My hope is to avoid exporting each plot individually and merging them later in gimp. It should be doable, especially if the html export does so implicitly?....Anyway, got ideas?

Thanks! ~A

> I would like to integrate the following expression that I call s2

 using the residue theorem. To do this I first want to find the roots (poles) of the expression. I do this by solving for the denominator equal to zero as below.

Hi--

I'm using Maple for an extensive research write up and need to somehow expand an extremely large function. The function is in terms of four variables, and each of those variables is either a function of x or a derivative of a function of x. I've attempted to use the "mtaylor" command, but it throws up an error when I try to input functions as my variables. I'm wondering if there's another way to do this. I've looked at using the "expand" command, but I don't see...

Hi, I am new to Maple, and, though I have scoured the internet and Maple's help, I have been unable to find a way to construct an element of F[x], where F is a finite field. Just to clarify, I am looking to construct a polynomial with variable x (eventually it will be multivariate, but I think I can extend to that easily), with coefficients from some finite field of size p^k, p and k being given.

I have seen a few examples online of people converting polynomials to...

I wanted to solve a pde system but I received this error.

hello!

i seem to have a problem with MatrixPower...

if i define a matrix such as

A:=([[-5,1],[-5,0]])

and use MatrixPower(A,k);

then i get the matrix A^k.

but, if fur example i do the following, i get an error:

A:=([[-5,1],[-5,0]]);

a:=exponential(A,1);

MatrixPower(a,k);

Error, (in LinearAlgebra:-MatrixPower) invalid input: LinearAlgebra:-MatrixPower expects its 1st argument, A, to be of type Matrix(square...

Could you tel me, is it possible to get free trial version of Maple 15?

Hello!

I have a problem that has to do with the function dsolve in Maple 14.

This is my code:

Hi all!

I got a task on multidimensional optimization. I need a full code in a maple of this method or method Rosenbrock. I first time see Maple and i have no time for learn syntax of this. (i know only delphi)

If anybody have this codes I would appreciate.

Good afternoon

I have just installed Maple on Linux - Ubuntu, but i have problems.

Please help me. how can i do



I understand this: 23 mod 4

 - it gives me the remainder on dividing 23 by 4

But how can I do the same thing with, say, 23.4 and 5.2?

The reason I ask is because I want to divide angles (float values) by (2*Pi) (another float) and just get the remainder, i.e. I want to discard multiples of (2*Pi) from my angle.

Hi,

Im using odeplot to plot the solution of a system of ordinary differential equations. I would like to extract the data to save them in a file. Ususally I use

a:=plot(...);

points := op([1, 1], a); writedata("file.dat", points, float)

But when a=:odeplot(); this is not working.
Can please somebody help me?

Thanks,

Javier.

How do I import/export excel into Maplesim? Also how do I view mpld data files? I tried viewing mpld files using maplesim and maple 14 but it didn't work.
