Hello,
I have some variables which usually have a specific value. I also have some parameters which are calculated using the previously mentioned constants. Sometimes though I want to change the value of the constants and re-calculate the parameters. Therefore I created a library with the initial values of the constants which I load inside a procedure which calculates the parameters. That way I can change the value of the constants and the initial values are not overwritten. My problem is that I want to export the calculated parameters and the value of the constants at the specific calculation. How do I do that_ I don't have an array, table or anything like that. Should I put my parameters in a table?

Thank you for your time.

Hi guys,

I am trying to solve for the roots in a polynomial of infinite order. The idea is simply to approximate the infinite polynomial by a high order Taylor expansion, solve for the roots in this polynomial (both real and complex roots exists) and use these roots as initial guesses for finding the authentic roots of the infinite polynomial in this specific range.

I have tried to use the evalf(RootOf(PolyInfinite=0,x,Re + Im)), however the output from RootOf seems to converge to the same 2 or 3 roots almost independent of the initial guess. Is there specific options of this RootOf function that can stabilize the solution or another/better command to use?

On the other hand i could solve this by simply minimizing a least sqaure, however i have not found any optimization solver which supports solutions in the complex domain?

I sincerely hope that you are able to help me.

Kind regards

Lasse

in maple 12

solve(a*b+a*c, [a(t), b(t), c(t)])

it return []

how to convert to a parametric form 

and then integrate them, 

and then convert parametric form back to f(a,b,c) ?

If I type in a function in 2D Math, the text disappears. for example, if I type fsolve(), until fsolve, the text appears, but after i type (, the whole text disappears. How should I solve this? Thanks.

Hello,

I am very new to programming and currently i am taking a course in numerical methods which allows me to get some exercise programming mathematical functions using maple. I am trying to plot a graph and it gives me an error. If anyone can guide me i would really appreciate it.

Also if there are any helpful advise for me to start using this language, it would be a big help.

Thank you

Just got Maple 18 on academic license. I've used Maple 15, 16 and 17 before this.

It wont write simple math symbols as + - * and := 

I have tried both document- and worksheet, reinstalling and so on...

What is the problem?

Thanks

Attached is my sheet.

On my system if just execute the whole worksheet maple return the last statement's integral un evaluated, however at this point if re-execute the statements from the definition of L2, it looks that maple has evaluated the last statement's integral.

What am I missing here, any help?

Regards!!

Consider the following two variable funtion:

f(x,y)=x^2+y^2-5

then we want to draw a contourplot:

contourplot(f,x=-10..10,y=-10..100)

My problem is that I want maple to diplay the value of the function "f" relating to each curve on the contour plot!
How can I do this?

Please see the following code.

I am using Maple 12 in Win 64. I have some difficulties in evaluating expressions in Maple. For example simply writing cos(x) then differentiating it w.r.t x. After writing cos(x) in 2D Math mode, I do right click for selecting diff but it does not work. The pointer turns in to busy mode and nothing comes to select. Also, I tried this operation in the tutorial file teaching differentiation, however problem persists.

Hello,

I'm looking to export the results of calculated variables to cells in a excel sheet.

For that purpose, I have used this code

with(ExcelTools);
Fichier:="Z:\2_Boulot\tabledeparametrage.xls";
Feuille:="Feuil1";
Export(xA1_Fus, Fichier, Feuille, "B3");

The error message is the following :

ExcelTools:-Export called with arguments: Array(1..1, 1..1, {(1, 1) = .3182057489}), Z:2_Boulot tabledeparametrage.xls, Feuil1, B3
#(ExcelTools:-Export,6): streamcall(INTERFACE_EXCEL_EXPORT(R,_params[2 .. -1]))
Error, (in ExcelTools:-Export) file I/O error La syntaxe du nom de fichier, de répertoire ou de volume est incorrecte
locals defined as: d = d, R1 = R1

Do you have idea why I didn't manage to export a result to a cell in excel ?

I think that it is probably because I don't define well the adress of my file. How do you define a the adress of a file which is contained in a folder on a harddrive in Maple?

Thanks a lot for your help.

Let's say I have 2 functions, the first being y=sin^2(x) and the second one is y=e^(-x)cos(x). When I try to solve on Maple, it only gives me one intersecting point, while I would like to see ALL intersections between the 2 functions. How would I go about doing this?

Good day, can any one help in writing maple programme for the finite difference (FD) formulae define to solve this coupled non-linear  ODEs. See it here FDM_programme.mw Thank you

Hi. It is be good to be with you after 4 years.

I want to ask about Curvefitting for Data. If I have a numerical data and i want to find a function in x and y for these data.
