I will post here the output of two commands that has me a bit worried. Of course it is entirely possible that I am overlooking something very simple, which is why I am writing to your site.

I have tried a program concerning an edge detector posted in 2005 by jan69.
The program works well till the end. I manage to have :

> Write ("edge.jpg", img_edge);

                             21108

But I don't know  how to find or create the new picture (after the edge detector).
Can you tell me how doing this ?

Hello,

I am new to Maple.

I have a set of spreadsheet data :(x1, y1), (x2, y2) .....(xn,yn).

And I have an equation that contains an infinite series with unkowns.

e.g.) y=  A*x + sum ( B * exp(-n^2 * (x-C)) /n^2, n=1..infinity);

Where A, B, C are unkowns, which I want to get optimized values for the spreadsheet data fitting.

Please let me know.

Dear Experts,

I am in a process of trying the roots of a sextic polynomial.

Attached is the equation type  sixthorderpolynomial.mw  . I tried to do some simplification. But still not able to find the solution.   I tried to use Factor also. But no progress.

I am intended to get the solutoin for lambda variable and remaining are variables are constants.

Hello,
I try to solve ODE. The resolution should be possible since I have found an article from which the calculations were done with Matlab.Here, I try to solve my system of equations diffs with maple.

When I use limit like this:limit(LommelS1(4.04, 3.04, z)/z^5.04, z = 0).The maplesoft shows:Float(infinity).How can I deal with this???,Please help me

Hi,

     I'm trying to estimate a very diffcult integral with Maple. Here it is

restart;
chi:=Pi/2-theta:
epsilon:=0.001: 

Vsi:=-(1/sqrt( 1+epsilon - cos(chi)*cos(phi-Pi/3)) + 1/sqrt( 1 +epsilon- cos(chi)*cos(phi-Pi))+ 1/sqrt(1+epsilon-cos(chi)*cos(phi+Pi/3)));

evalf((Int(Vsi*SphericalY(3,2,theta,phi)*conjugate(SphericalY(2,1,theta,phi))*sin(theta), [theta=0..Pi,phi=0..2*Pi])));

I ultimatly want epsilon->0,...

How does one view the Maple code that controls embedded components in a worksheet? I've looked at every menu on the toolbar and every context menu I could find, but nothing seems to fit.

I got the following error message when trying to execute a maple code:

"invalid character in short integer encoding 69 E"

I can't find anything about it in the maple documentation, does anyone have any idea what it means?

Thanks.

Hello guys ,

I found critical points for a 3-D dynamical system (x,y,z) and m which in general is not constant (m(z/y) is a function of z.y, when i calculate eigenvalue for every critical point ,the maple assume m constant . how i find eigenvalues for general m which is not constant and is a function of z/y .

Thank You

Dear Maple experts,

I have a function f  depending on three variables a,b,c i.e.   f(a,b,c).

I have to find the df/da (differentiation  with respect to a) and then solve for variable a in terms of variables b and c to make the f(a,b,c) into f(b,c). 

However, I am not able to find the symbolic relation from df/da to represent variable a interms of variables b and c because the solve(df/da, a) is...

A beam of neutrons bombards a reactor's wall. Consider the motion of the neutrons as a random walk on the (x,y) plane.

The neutrons then have to comply with the following conditions:

1. Only four directions of motion are possible (left, right, up or down).

Hello all.

            I want to execute a particular section of my legthy code, after certain lines I want that let Maple not execute further. It could be a possibility that after those ceratin line I may execute my code further. I dont want to comment those lines as some later stage I may use them again. Is there any command which can fulfill my purpose.

Many thanks in advance.
