I believe I have located the relevant help page,

http://www.maplesoft.com/support/help/Maple/view.aspx?path=worksheet/documenting/setautoexec

The method is not as versatile as I'd hope. It doesn't seem too useful for my purpose, because I intend to frequently change those sections of the worksheet to be marked.

I was looking for a feature more along the lines of:...

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?

Dear all. Consider I want maple to solve an ODE for ten different initial conditions in a for loop and I don't want to write all details for me. I just want maple to show me the number of for example n-th of ten. I mean when maple starts to solve, show me number 1 and when solves the ODE for the first initial condition and start to solve ODE for the second initial condition, the previous 1 change into number 2. Thank you. 

Has anyone noticed Maple 15 is sometimes very slow to launch in OS X 10.7 ?

Hello, I'm having trouble running my worksheet on my computer, don't know why but the Solve commands just never give me output, even with easy equations.

If someone could please run this worksheet FormulasToSolve_2.mw   for me I would be greatly thankfull, I'm stuck in my research because of this...

Hi there,

I am working on a Maple sheet where I've been doing all the calculations with units. The problem is that I now want to get the product of a "seq" "R_DC_total-sek" and multiply it by the sequence R_AC_total-sek. But how do I do that? I've tried changing them into lists, but since one of the lists have units and the other one do not, Maple does not multiply the two lists, but just prints them.

I've uploaded the sheet here:

Thanks for your attention firstly. I want to plot the error function between the exact solution and numerical

solution. However, there are some errors. Here is my procedure. would do you like help for this procedure?

restart:

Digits:= 32;
u := 1;
w1 := 10;
w2 := 5;
ode := diff(y(t), `$`(t, 2)) = u*(1 - y(t)* y(t))*diff(y(t), `$`(t, 1)) - y(t) + t*exp(I*2*w1*t) + t^2*exp(I*2*w2*t):
ics := y(0) = 1:

Good Morning.

I have a problem

i have two functions

> xcir(t):=0.3 + 0.15*sin(t):
> ycir(t):= -0.3-0.15*cos(t):

and i suppose that i have a problem in the following equation

> qd2 := ((arctan(-ycir(t)/xcir(t))-arctan(.45*sin(qd3(t))/(.45+.45*cos(qd3(t)))))*180)/(3.1416);
> qd3 := 180*arccos((xcir(t)*xcir(t)+ycir(t)*ycir(t)-.45*(2*.45))/(.45*(2*.45)))/(3.1416);

New to maple. Trying to solve system of four difference equations for four variables in the form:

Keep getting "warning, solutions may have been lost".

Any suggestions on where I go from here? The solution I know exists is not returned in the list of solutions.

Thanks
