My mathematics computation relies on a loop.

That loop is heavy and takes very long time to finish.

I try to split some undetermined functions outside the loop so that the work inside the loop will be easier.

I don't know how to use proc or module. Is there any tutorial that can help me as a beginner on this part?

Basically i need maple algorithm that enables user to call a user-defined function from another function.

And also how can...

I have to write a procedure that finds four positve numbers with a two decimail digits such that their sum and product is equal to 7.11. i.e a+b+c+d=a*c*b*d=7.11

I know i have to use loops but I have no idea how to start

please help , my deadline is near

Hi

I am trying to model the change in lifetime versus mass and have the formula;

> T := 6.58*10^38*10^(-25)/x^3;
                                      
> plot(T, x = 10^10, 10^9, 10^8, 10^7, 10^6, 10^5, 10^4, 10^3, 10^2, 10, 10^0);
Error, (in plot) unexpected options: [x = 10000000000, 1000000000, 100000000, 10000000, 1000000, 100000, 10000, 1000, 100, 10, 1]

I want to plot for values between x=10^-11 and 0, i have this error and i am not sure why.

I have come across a missing rule that Syllable length does not take into account.

with(StringTools):

SyllableLength("raked")
                 2
SyllableLength("rakes")
                 2
SyllableLength("baked")
                 2

While looking over some old Maple 9.5 applications I came across two applications requiring the HPC Grid computing toolbox for maple. 

Now that parallel computing is becoming the norm and parallel code tools are included with newer Maple versions.  Has this toolbox just been integrated into Maple?  or are they two totally different entities altogether.  I am sensing the toolbox is to deal with multiple computer systems as the parallel code tools...

Hi

I solve a mechanical exercise but i had a problem.

I know M (mass) and S (stifness) matrices (6x6).

I want to solve the (λ²M+S)v=0  eigenvalue problem, where λ are the eigenvalues and

In a string, how can I find a letter of both upper and lower case?

Hi all,

Is it possible to get convergent solution in the coupled equations, here i have attached my file , i want to solve equations to get a value for f ' and theta , i am solving these two equations using pade approximant with limit tends to infinity, in my worksheet im trying to  solve coupled equations, is that coding is correct or still there is any possiblity...

Hi, this  must have been asked numerous time, but I cannot find it in MaplePrimes:

How does one "collect" sqrt terms? collect(expression,sqrt) does not work because sqrt is actually represented as ^(1/2) in  Maple. collect on '^' does not work either... ??

Hey guys..

I need some help on determining the correlation coefficient between my data points for an Influenza epidemic and the SIR model, with my estimated parameters Beta and Alpha. The initial conditions for the equations are defined at the beginning of my worksheet:

Hope someone can help me ;)

Hello,

I am working on a Maple project and it require me to pass a differential equation in a specific order like

x'=y & y'=x^2.(It is differentaiting w.r.t 't'(say))

However when I convert the equation into string it converts something as

diff(x(t),t)=y(t) & diff(y(t),t)=x(t)^2

Is there any way to stop maple from evaluating into maple/math format?

Is there any way to pass an equation without changing it's existing form?...

I had MAPLE 12 on WINDOWS VISTA machine and the harddrive crashed.  Now I have a newer WINDOWS 7 machine & would lke to put my individually licensed MAPLE 12 on this machine.  I do not have a DVD because the original installation occurred via MAPLESOFT website if I recall correctly.

Can anyone direct me as to what I need to do?

THANKS

Hi,

I'm having some problems with the generation of the typical stiffness matrices seen in FEA formulations. I have got an elementary matrix that is looped through the entire stiffness matrix to generate it. As there is juxtaposition between the elementary matrices, there is some recursive assignment involved that I can't handle properly. Here is the code for a 6x6 elementary matrix with a 3x3 juxtaposition. n is the nombre of recursions needed to fill the stiffness matrix. M is the elementary matrix

On my keyboard, Cntrl = action for evaluating an expression inline does not work. The reason is that = is the upper level action (with the shift key) on a key with 0 at the lower level. Doing Cntrl Shift = does not work either. How do I get this done on my keyboard?
