Is Maple able to solve a 2nd order Hyperbolic PDE numerically, with some complex initial/boundary conditions?  what about Mathemaica?

I appreciate any help.

 

Dear Forum,

this is Vista related.

Maple creates a Maple folder(containing the Maple.ini file) in c:/Users/<username>/Application Data.

Ist it possible to tell Maple to create for this folder in a different place, say c:/Users/<username>/AppData ?

 

Thanks

Is it possible to compute possible addition chains for an integer in maple ??

If not, is there ANY software that will do it ??

It looks like, choosing a public key exponent with a smaller addition chain makes  RSA decryption more efficient .. but how to know whether or not your exponent has a small addition chain!

Hi all

i've been trying to solve 2 equation with two variables. I got 3 solutions which are complex, i.e. a list  A:=[[ x = ... , y = ...], [...], [...]].

now, A[1,1] gives me the x of the first solution, and I want the real part of it. But when I write Re(A[1,1]) it gives as an answer R(x) = R(...). the problem is that afterwards I need to use this number (for emaple, in pointplot() ), and Maple doesn't let me.

How do I extract the number itself from Re(A[1,1])  (and not a string)?

thanks in advance

 

i have manged to plot a 2d and a 3d phaseportrait. not my question is how i can add a line to the plot in order to show the zero isocline lines in the same plot?

How do I compute a Groebner-Basis auf a Ideal I that corresponds to the SINGULAR-command 'std'?

Hi there!

In Maple 9.5: when programming you were able to ident code using the TAB-key. However in Maple 12 (when not using the classic mode) when programming you have to use the space bar several times, the TAB-key won't work.

Any thoughts?

There is some interesting news in the Business section of today's Kitchener-Waterloo Record newspaper.

Cross-referencing, there is a press release.

i want to read a file from maple and then hav solve it in matlab numberically, can any  one help in this regard

Hey, I am using Maple 11 to numerically solve for coeffiecients in a system of nonlinear equations, and I need to use the solution elsewhere in my procedure, but the return from fsolve looks like: coefficients:={j = -139.55659155625, k = -3.8511665004543} and I can't access the actual numeric values since coefficients[1]; returns: j = -139.55659155625 when all I want is -139.55659155625. I am sure there is a simply solution but I haven't had any luck finding it. Can anyone help me? Thanks Kyle

dear i have very complex problem may it wil easy for somone, i have 36 equations in maple that i have to use in matlab to simulate and the equations have to take som numercal values in matlab, and it has to generate some numerical values while running in a loop. i have used the with code generation option in maple. and it produce a code for matlab.

Hi,

given a n*n Square Matrix (n is known), what is the easiest way to calculate all minors of this matrix ? There is a minor command in LinearAlgebra, but it seems to refer only to the first minor, that are the determinants of the reduced (n-1)*(n-1) Matrix. But I want the minors of a given size, specified by me. An application would be a test of definitness (Sylvester's Criterion). Using Maple13

 

Thanks

Good Afternoon,

Would anyone help on how to assign equations in a list to an index variables in a list. Below is my equations.

Eq := [seq(A[i], i=3..n)] = [seq(M[i -1]*a/(6*E*Ipile) + 2*M[i]*a / (3*E*Ipile) + M[i + 1]*a / (6*E*Ipile) - (Delta[i - 1] - Delta[i]) / a - Delta[i] - Delta[i + 1] / a ) = 0 ), i=3..n)]

assign(%)

When I tried the above, I was expecting Maple to assign A[3]  to the first equation in the list on the right hand side and so on, but instead I was getting an error message.

Dear Sir / Madam,

Attached is copy of worksheet developed in MathCAD that I would like to develop in Maple. I have copy and paste what I developed in MathCAD into a Maple worksheet to see if any body can guide me. I have posted previously an excel file with Canadian steel sections on Mapleprimes. My goal is to be able to auto select  a  steel section from the database into Maple for computation.

Please, would anyone guide me as to how to develop the attached worksheet into a Maple worksheet.

 

Regards
