Dear all, 

I'm using the maple command in MacOS. While doing some computations, Maple periodically prints out the GC information such as:

memory used=444.9MB, alloc=184.7MB, time=7.75

I'm wondering how to tell Maple to only suppress those information? I also noticed that maple has an option -q to suppress such information, however, that option is too powerful which suppress other useful pretty printings too, which is not what i want.

Thanks,

hi, in following commands what is wrong :

s define before. i sure it's error related to dsolve. i want to have f[i](x):= dsolve({s[ii], ics[ii]})

for ii from 1 to 6 do ;
ics[ii]:=f[ii](0)=0,D(f[ii])(0)=0,D(f[ii])(10)=0;
ans := dsolve({s[ii], ics[ii]}) ;
 f[ii](x):=ans
od:

thanks

hi

i want to write these commands in maple but i dont khnow how to wirte :

do i=1,10

ans = i*2

f(i)=ans

end do

above code written in fortran patern and i want maple patern. for example i try these command but it doesnt work.

for ii from 1 to 10
 do ii*2
 f[ii](x):=%
end do

I'm looking for an older worksheet called something like 'Basic Jet Engine Model' originally created for Maple V. 

Does anyone recall such a worksheet?

Hi all,

 I am trying to solve a system of pde's to get an analytical solution in maple. here's the system:

pde1:=diff(Ti(r,t),t)=(1/r)*diff(r*diff(Ti(r,t),r),r);

bc1:=Ti(r,0)=1,D1(Ti)(0,t)=0,D1(Ti)(1,t)=D1(To)(1,t);

pde2:=diff(To(r,t),t)=(1/r)*diff(r*diff(To(r,t),r),r);

bc2:=To(r,0)=0,D1(To)(1,t)=D1(Ti)(1,t),D1(To)(1.5,t)=0;

sys:=[pde1,pde2,bc1,bc2];

sol:=pdsolve(pde);

Error, (in pdsolve/sys) the input system...

In Maple (v13), how can you present a step-by-step solution in a document where each step :

1. Follows on from the previous line;
2. The equal signs are (vertically) lined up underneath each other; and
3. There may or may not be a LHS (there isn't if the LHS hasn't changed).

I suspect you need to use a table, but with this idea in mind I still cannot work out how to do this.

Hope this all makes sense.

[moderator edit:...

I have no idea what happens here:

restart;(a+3)^17;expand(%);

s=05189CFC, invalid INTPOS

Error, (in Typeset:-Tdisplay[true]) object at address is invalid
                     Typesetting:-mi("` `")
Error, unexpected result from Typesetting

I have Maple 15.

I've recently uploaded an application to the MAPLE Application Centre:

http://www.maplesoft.com/applications/view.aspx?SID=121124

I have since tried to make edits to the application and to submit them using the edit facility there, but none has been implemented. Please would some one let me know ne who can help resolve this problem?

Hi. I have a function defined like this: 

myfun := proc(a11 ......)

f := a11 * x^2 + 2*a12*x*y + a22*y^2 + 2*a13*x + 2*a23*y + a33;
printf("\n");
 printf("%a",f);

 end proc; 

When i call this function from my worksheet, the "f" polynomial is printed unformatted. For example the output in my worksheet is

x^2+6*x*y+y^2-2*2^(1/2)*x-6*2^(1/2)*y-4

i use symmetric function package

with(SF):

i would like to know after calculating the basis toS(....)

which function can be used to convert into polynomials?

as i expect to get the sequence from any polynomials generated from it

refere to http://www.maplesoft.com/support/help/Maple/view.aspx?path=PDEtools/SymmetryTest

1. What is the purpose of using SymmetryTest for PDE?

2. What is the purpose of using infinitesimals?

3. What is the purpose of using InfinitesimalsGenerator?

4. Any documents or books mentioning above in detail?

Hello, thanks for reading this:

I have a bunch of points (x,y). I turned the points into a graph and then asked maple to give me the equation to the line.

It's mostly accurate however,..it's not close enough.

When I test the equation I can see some deviation from where it should be.

In some places the deviation is rather significant.

Does anyone know what I can do to get this more accurate??

Thank you!!!

Hi:

I am running a home network, XP and Maple 11 on the old computer, Win 7 and single-user Maple 15 on the new.

It took a long time, but I finally got a wireless network running, so that Win7 on the new computer can open and access all the files on the old computer.

But when I run Maple15 on the new computer and try to open an old computer file, Maple 15 cannot see the old computer or any of its directories, even though it has a "network" tab on the "open" command.

There was a lengthy series of posts [link], in late 2008, concerning the paper of Demetrios Panyotounakos that claimed to have solved a large class of Abel equations.  As I read the posts, it would seem that the final conclusion had not yet occurred, as to the validity of his claim. 

In particular there were questions to Edgardo Cheb-Terrab as to why this...

Hello everybody,

I'm quite new to Maple. I need to get the relative values for two variables in an inequality. I thought using Maple would be an easy way but instead I'm getting confused.

I tried this command:

solve((2+l^2-4*l)*n^2-(4-4*l)*n+2>0,n);

and the output I get is just the error about lost solutions.

Is there anything wrong with my command?

Any help is appreciated and many thanks in advance,
