i copy the example to run in a new project, it can run successfully

however, after copy part of code such as static class MapleEngine into my old console program, it return error unable to find maplec.dll when run at StartMaple

this old project is created with Visual Studio 2008 and migrated to 2010

then i do backward, i succeed when i copy old console code to new project which can run maple

this project is newly created in Visual Studio 2010

Hi, I’ve recently begun using Maple 16. I just discovered a problem when trying to open my saved files. I can’t open them directly form the folder where they are saved, I get a Message saying: File XXX.mw could not be found, please select another file. I can accsess the same file through the recent files form within the application.

It is not a shortcut, but the original file I'm trying to open.
If it matters, I'm using windows 8 

I'm looking for any procedure to calculate orthogonal latin squares. I found this:

rOrt := proc (A, B, n)

local freq, i, j;

freq := Array(0 .. n^2-1);

for i to n do

for j to n do

freq[A[i][j]+n*B[i][j]] := 1

end do;

end do;

freq := convert(freq, list);

return numboccur(freq, 1)

end proc:

But I don't know what I now have to write to see result, for example for n=3?

Aslam-ul-Alikum I need some help urgently. I want to compare the coefficients of like powers of Y_1*Y_2, please help how i compare it in maple

Find , continuous such that

I thought I would generate a fun problem for Maple, and see what coding we could come up with.

You happen to be at work one day and overhear the managers talking about taking sick days away from the employees because everyone is taking their sick time around weekends.  The managers have decided to take one more years worth of data before making their decision. 

So you've decided to build a program in Maple for all the employees to use so that...

Hi, I got a doubtI don’tknow how to make the Runge-Kutta’s and Euler’s method. The Runge-Kutta for thesecond and fourth order. I don’t know how to beginning the algoritms, I needsome help. Thanks.

Now I compute the integral 

0<int((abs(c-x)/x)^n,x=a..b)=int((c-x)/x)^n,x=a..c),symbolic)+int((x-c)/x)^n,x=c..b)

assuming c>0,b>c,n>-1.

As it is not possible directly, I split this apparently real integral in two parts. Both parts are real for n>0. Look, what's happens!!!

> Za:=simplify(int(((c-x)/x)^n,x=a..c),symbolic) assuming a>0,c>a,n>-1;

When I do integration and differentiation, even of the simplest functions, it gives me incorrect answers. What could I have done wrong? Just to mention I recently installed a licensed copy on my computer. 

Hello

pl explain me how to find a and b in this eqation

a^x + b^y = 1,

were a= 5 and b= 8 

thanks

I want to invlaplace the following complex expression that I call PQ.

>PQ:=(cosh((1/2)*eta*sqrt(C3^2+4*C1*s))*sqrt(C3^2+4*C1*s)+sinh((1/2)*eta*sqrt(C3^2+4*C1*s))*C3)*(cosh((1/2)*eta*C3)-sinh((1/2)*eta*C3))*(-cosh(C4)-sinh(C4)+s)/(s^2*(-sinh((1/2)*C3)+cosh((1/2)*C3))*(sinh((1/2)*sqrt(C3^2+4*C1*s))*C3+sqrt(C3^2+4*C1*s)*cosh((1/2)*sqrt(C3^2+4*C1*s))))

where C1 C3 C4 eta are constant .

Then I do like this

>invlaplace(PQ)

But I got

I have problem with externall calling. I need to return from java 2-dimensionall array. In java class it works fine, but I can't find proper definition in Maple, done by define_external function. I tried also return 1-dimensionall array, but there I didn't have problems.

My code in java looks like:

public class ConcatTest2{

public static int[][] Test(){

int[]][] ret = new int [2][1];

Hello, everyone, I have written 13 equations, and some of them contain 88 items at least, so they are complicated. When I have executed the program and estalished input and output ports, I click the button "Generate MapleSim Component", it takes a while for running, but there is no MapleSim Component generated in the GUI interface, strangely, no error information appears at the same time, I cann't figure out what's wrong with it? Could someone help me out? Thank you. This mw file is attached.
