Dear guys! I'm solving a system of ODEs in a for loop with different initial conditions and after that in each loop I use the result to solve an integral and after all I find the minimum value of integrals. But the problem is that when I write for loop with for example 100 initial conditions I get a result and when I expand the numbers to for example 1000 initial conditions where include the 100 previous one maple tell me that the initial conditions that make the integrel minimum are the same ...

Dear guys! I'd like to know that for solving an integral by maple we have to use " int " or we have any other choices? Because I have an integral with large limits from 0 to for example 1000 and it takes much time for maple to solve it.

Using the tree structure example from ?GraphTheory[DrawGraph] using showlabels=true the highlighted areas are merged and no amount of zooming can seperate the merged yellow areas.

Another issue, I don't see the advantage of style=tree when a tree structure can only be printed if the original DrawGraph is already represented as a tree style structure when...

I would like to solve x1v for funcF1(funcr(x),x)). I did similar computations before. 

I think Maple can deal with rational functions very well. It's having a trouble to

use the common denominator the simplify x1v. 

> denom(Wx1v);
                    2           2                            2
               -barv  + funca(x)  D(funcP)(funcr(x)) funcr(x) ...

Hi all,

I have two plots, one done in Maple and an other in Matlab. And I want to compare the two plots with superposing the two plots in one plot (in Matlab or in Maple).

Copy from a plot in Maple and past into a plot in Matlab don't work.

What is the easy way to do that ?

Thanks in advance

I'm new to Maple, can anyone advise on the best way to create Quiver plots?

Help!

I've used Eigenvectors to solve for eigenvalues & eigenvectors.  Eigenvalues works, no problem.

The eigenvectors are not normalized to unit magnitude (how would I do that for all eigenvectors?) and the usual matrix multiplication of the eigenmatrix by its transpose should give the identity matrix--and somehow it does not. 

Can someone point out the flaw in my thinking?  The file is attached.

Thanks for you insight! 

Firstly, I need solve q(t) by the following procedure:

u := 8.53;
dsys0:={diff(q(t), `$`(t, 2)) = u*(1 - q(t)*q(t)) * diff(q(t), `$`(t, 1)) - q(t), q(0) = 0, D(q)(0) = 1};
dsol0:=dsolve(dsys0,numeric,method=rkf45,abserr=10^(-10),relerr=10^(-16),range=0..6,maxfun=0,output=listprocedure);
yy0:= eval(q(t), dsol0);

Furthermore, I need substitute q(t) into two second order differential equations for solving yy10 and yy01. The procedure is

I recently purchased the Student Edition of Maple 15 over the internet. I accidentally downloaded the 32-bit version, is there any way that I can download the 64-bit version? I can't seem to find this option on the website.

Hello all ,

I have the following code to do my calculations and it runs fine for one set of input values ,

A=a1,a2,a3

B=b1,b2,b3

C=c1,c2,c3

For example right now the sequence lets me solve for corresponding set of input values like (a1,b1,c1) ,(a2,b2,c2) and so on

What i am trying to do is to solve for (a1,b1,c1),(a1,b1,c2),(a1,b1,c3),(a2,b2,c1),(a2,b2,c2),(a2,b2,c3) and so on...more like seeing the...

HI,

I have been trying to convert a small script (Maple 15) to latex but ran into a strange problem. Literal subscripts don't seem to work.

When I have, for example " f_a " latex will generate a pdf, as expected, with " f_a ". However, if I have " f(ctrl+shift+_)a " I get "  ‘#msub(mi("f"),mi("a"))‘ ".

I am kind of new to this maple+latex thing and have searched everywhere for a solution but without...

In Maple boolean evaluation returns the values 'true' or 'false'.

Is there any canonical way of getting evalb to produce values in {0,1}? This is of some use when testing conjectures on  hudge lists of items...

Of course: you can always define a script like

###########################
evalbb:=proc(PP)
if evalb(PP)='true' then eps:=1:
else eps:=0:
fi:
eps;
end:
###########################

but I think there should be...

Is Maplesoft planning to release a 16.0 version in October 2011? 

do maple have tree data structure for genetic programming?
