Dear Maple Specialists,

I deal with a major MAPLE problem the last months of my PhD.

PROBLEM:
My programm contains a do loop which calculates for given PsiS (purple color) and for a range of Psi1 and Psi2 (blue color) from PsiS to 0, values for the products Qsu1, Qsu2, Q_tot .
The aim to calculate w(RLZ) which is obtained when the blue color loop is completed and Psi2 takes the final value 0.

Hi,

I am working with equations on Maple which depends on a parameter (epsilon), which can assume only the values +1 and -1 (I intent to replace this value only in the end of calculation). When, however, Maple computes the expressions, the result contains severals powers of epsilon, for instance epsilon^7 or epsilon^4. Since actually we have that epsilon^7=epsilon and epsilon^4=1, respectively, it would be very usefull to me if Maple 

After loong time calculations i obtained results and manually fitted them. Of course, as usually happens, kernel broke and all i have is output (output in rtable form). So i decided simply export-import them and continue my manipulations.

All i see is "export to ml form". So i did it. And after that i tried to reimport them via

MathML[Import]

HI,

I want to create a Textbox which will be opened in the beginning of a Maple code. In this Textbox I want to write an integer, which will be used for a following calculation.

I already found this code:

> restart; with(Maplets[Elements]);
print(`output redirected...`); # input placeholder
> maplet := Maplet([["Insert Text", BoxCell(TextBox['IB1'](1 .. 10))], [Button("OK", Shutdown(['IB1'])), Button("Cancel", Shutdown())]]);

I have been using Maple in Document mode to provide documentation of engineering calculations according to various design standards.

I have been asked to provide more detail about certain critical calculations.

Ideally, I would want to enter the formula as a symbolic espression, then the output would begin with and echo of the expression with numberic values substituted for the variable names (ie without performing any mathematical operations), and then give the evaluated answer.

As usual happens in symbolic calculations - small change of input parameters leads to drammatical change in consuptions. I had talk about many other partial issues in  this forum. Many other issues i just tried myself without any success (for example try convert(exp(x)+x, FormalPowerSeries)) and now i must take decision: wheather or not to continue work with maple at all. It's totally clear for me that others (like Wolfram mathematica) not much better. Only one other...

How to speedup them? There are more than 20 functions that are evaluated one by one. Is option 'remember' + permanent remembered item of pure symbolic calculation can speedup this process? How also efficiently to do simlify itself? Can i actually use more kernels in one session or to paralilize available one?

Hello, I have a problem, when I define some constants like a:=5, b:=6 and than I do some calculation like a+b maple shows immidiately the solution. Is there any way how to make maple to show the numbers at first and then the solution? What I mean is if I define the same constants a:=5, b:=6, then make the calculation a+b. The output i want would be 5+6=11. Is it possible to make maple show the solution this way? I use it for more complex calculation in civil...

Hi,

I am working on my project related to bioinformatics. I am using Maple 11 for calculations related to matrices.

I need to calculate  Moore-penrose Pseudoinverse. I need to know the algorithm used by Maple function

'MatrixInverse' for calculating pseudo inverse of matrix.

Thanks

Hi,

I have the function:

restart: with(plots): with(OrthogonalExpansions): with(DiscreteTransforms):

f:=t->piecewise(t<0,0,t<1,t,t<2,2-t,0);

The Fourier coefficients a[0], a[i] and b[i] can be calculated by:

T:=2: Trig:=FourierSeries(f(t),t=0..T,n,'Coefficients');

a[0]:= op(1, Coefficients);a[i]:= op(1, op(2, Coefficients))[1];b[i]:= op(1, op(2, Coefficients))[2];

I want to calculate those coefficients a[0...

One useful feature of the `evalf` command is that it remembers previous results. But it also stores the current value of Digits as well as its input argument, to be associated with the remembered result.

There are two reasons for this. The fancier reason is so that, when Digits is reduced from that of an earlier successful computation, `evalf` can simply round off the earlier result to the desired number of decimal digits. The more basic reason is that `evalf` might...

Hi,

I am using maple x64 to read/ open some large TIF files.   The files are 57 Mb each and I want to open 16 of them.  Maple looses kernal connection twards the end of the calculations each time.  This is anoying. Is there a way to fix this?

If I take the result form y and defign it as y and delete x them maple will calculate 1 more function set.

document setup;

x=read-image (using the actual maple commant)

y=entropy (x...

Hi,

I am new to Maple and doing a trivial calculation raised a few questions. I tried to calculate the average density of a wire with the following specs: 

• diameter = .40 inches
• length = 1000 feet
• weight = 61 pounds

Here's what I have come up with. 

with(Units[Standard]):

wirediameter:=.40[inch]:

wirelength:=1000[ft]:

wirevolume:=(wirediameter/2)2 * Pi * wirelength:=

please check its hardware details !
and tell me usually a laptop with this condition ...

Hi!

I'm sure there is a simple solution to my problem, but because I'm fairly new to using Maple, I can't figure out why my graph won't work. All I'm trying to do is graph a function along with its first and second derivatives within the same graph. The original function is f(x)= (2+sinx)^x²/(x²+1).

I defined the function as f and then found the first derivative by using df:=D(f...
