Having a little trouble getting Remove to work properly in Maple 12

a := "Just try to remove a letter using Maple 12's StringTools[Remove]";

with(StringTools);

Hi,

I was trying to find the generalized eigenvalues for the (3x3) matrix pair (P,G) defined below. (I have left everything in symbols with beta and kappa both of which are strictly positive real numbers). For some reason the command Eigenvalues(P,G) is only returning 2 generalized eigenvalues. Any ideas why it doesn't return 3?

Thanks,

Lee

Hi!

I want to write the following textfile in a matrix of the size 4x24:

      1    0.5    0.5      1      1    0.5    0.5      1      1    0.5    0.5      1    0.25    0.25   ...

Hi all,

I have a strange problem with the Classic worksheet in maple 15. To explain the problem i added an image.

when i want to plot vergl_6 without copying the equation i get an error. But when i just copy and paste equation 6 like i did everything works like i suspect.

Can anybody tell me the problem? I need to...

Modify the shortest path problem by rewriting a procedure Path, non-Recursion
 that print out the shortest path from a to e base on the information from 
 setShortestDistNode
 input:  destination "e" and setShortestDistNode
 output:  path : a -> b -> d -> e the total cost: 9
hint: copy everything that we did in shortest path problem, and rewriting a procedure Path, with while loop 

can...

write a procedure to remove all repeating elements from a given list
input:     a list with  repeating elements, such as [1, 5, 4, 1, 2, 4, 5, 1, 6]
output:   a list without  repeating elements
note: use list as your only structual datatype, can't convert it to set

hint:  you may use maple function has, no srting needed.

can someone help me on how to write this ? thank you

How can we import data directly from a zip file?  Does someone know how to?

Dear Maple Users,

I'm beginner in Maple and I will appreciate any help and guidance.

I need to integrate function (which values vary in wide range) on the specified domain.

Maple returns Float(undefined) error. Is there any way to overcome this?

the question is in attached Maple file mp_qsn.mw

Thank you in advance.

Trying to plot a 3-d plane of random numbers.  How do I index the matrix A in plot3d? 


> with(RandomTools);


> A := Matrix(2^5, 2^5, Generate(distribution(Normal(1, 0.1e-1)), makeproc = true));

> plot3d([x, y, A(x, y)], x = 1 .. 32, y = 1 .. 32);

While substituting expressions for θ(t),θ'(t),θ''(t) with some rather simple polynoms (see attached demonstration), the result icludes terms such as "·²" or "θ1·" (see terms multiplying ε⁸ and ε⁷in result for C1). It seems MAPLE treates the "·" sign as a variable/constant instead of as an operator. What am I doing wrong?

Hi, when i use the "export" function to export a set of matrix, it works fine.

But when i try to use it to export one number, it won't do it for me, for example the value of a, where a:=5

Export(a,"File1","aValue","A1")

How do i export one value? please help. Thanks.

I installed M16 32 Bit on my new machine with Win7 64 Bit.

But the following results in crushing mserver.exe:

  tmp := proc( x :: float ) :: float; 2.3 * x end proc:
  cp:=Compiler:-Compile(tmp);

with system info below. 

Do I have to set certain rights for the compiler or define a specific working directory?

The FAQ http://www.maplesoft.com/support/faqs/results.aspx?search=compiler does not help me.

restart;

pde := diff(u(x, y), `$`(x, 2))+4*(diff(u(x, y), `$`(y, 2))) = -x*y;

ibc := {u(0, y) = 0, u(2, y) = 0, u(x, 0) = x*(4-x^2), (D[2](u))(x, 0) = 0};

sol := pdsolve(pde, ibc, numeric);

sol:-plot3d(x = 0 .. 2, y = 0 .. 1, numpoints = 2000, axes = boxed);

The final command produce a figure with some sigularity.

how to fix it? I need help, thx you very much.

I'm sure there are other Maple users who have done these things, but I'm in the early stages of learning Maple 15 after moving (up) from Mathcad.

1. How do I plot a simple wireframe map of the world?

2. If I have a dataset of gridded data where the data is in the form [latitude, longitude, number] how do I map that data to a grid on the globe and give it a height according to the magnitude of the [number]?

3. Is there a way to smooth the heights of each...
