how to rewritten the PDEs to the matrix form like the following in Maple

Thank you for suggestions. The system in matrix form looks like z(k+1)=Az(k). The solution to that is z(k)=A^kz(0). Now, phase planes of the system would look different for different matrix A (specifically, eigenvalues of A). For example, for complex eigenvalues phase plane would look like a spiral. I'm having difficulties plotting those phase planes. It's easy for differential equation, but I'm not sure how to work with system of difference equation in Maple.

I have attempted making a translation the Wolfram Mathematic's document: Singular Value Decomposition.
I present Problems in showing the arches of angles. Besides result do not correspond .

Is there any way to modify the shading colors used in shading=zhue? 

Maybe similar to what was done in the post for Color of the plot of convex hull of points or perhaps there is simpler way?

Hi All,

I have a question that I see has been seldom discussed except certain posts by Mr. Lopez. This concerns the estimation of optimum parameters of the solution of a system of differential equations to fit experimental data. I referred to the Maple document provided by Mr. Lopez on the Maplesoft website.

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.

Please help me.

P.D.: I send a worksheet 01-06-2011-robot-man.mw

I have a pbs: Suppose 3 vector A, B,C with noted [A:B]:=(list)[ A,B,-A,-B] (i.e a paralelogram);

An endomorphism T such that T(.) where (.)=A,B or C are B,C, and (list)[C,-A,-B,-B]
 and T([x:y])=[T([x]):T([y])] where x,y = A,B or C.

Problem: draw T^{n}[A:B] , i.e its boundary is a fractal figure when n is big.

Hi everyone,

I am facing a very complicated system of nonlinear equation. This cannot be solve by using normal fsolve in Maple. Anyone can help me?

Thanks a lot

I  used the DEtools package recently.

When working in a differential algebra with _Envdiffopdomain=[Dt,t] maple still returns something like Dt t^2. I would like him instead to assume, that Dt= dt/t and rewrite it as 2t + t^2 Dt. How can I achieve this behavior?

Hi , I'm Alan GHafur , I'm student in master dagree in Statistic in Irbil / Iraq .I want learn how can slove non linear function in Maple.

thank you for hlep me.

In 2D input it is possible to represnet

diff(f,x) as d/dx f

Is it possible to do

diff(f,x,x) as d^2/(dx)^2 f somehow?

Can one perform animation using the data file.

I want to animate the graph betweeen two variables say x and y, which I have stored in a data file. Does maple support any such operation?

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

Hello,

I have this problem. I would like to construct clothoid as a transition curve between two arcs. The length of this curve has to be 30 meters. The start azimuth is 0.3773 (rad) and the start radius is -355.835 m.

How could I do that simply in Maple?

Thank you
