I'm having problems tweaking legends in plots. I'm using Maple 15 / Standard on Windows 7 - 64 bits.

The first problem I have is that the legend box is too narrow. Is there a way to fix that? The help page does not mention anything to that effect.

http://www.maplesoft.com/support/help/Maple/view.aspx?path=plot/options

I could have the legend above or below and the box would stretch wide enough, but I would prefer to have the legend on the left.

I am trying to get students to study inc/dec etc. with a function like y = 3/5* x^(5/3) - 1/2*x^(2/3)

the problem is that Maple will NOT plot either the original function or its derivative, except where x > 0

this does not make sense to me, since of course a cube root exists for x < 0.

Please HELP !!!

thanks

PS I use Maple V at home, at school Maple 11, classic work sheet

There is a enought complex function H(y) of one variable (includding definite integrals and 3 parameters). One needs to solve equations like that H'(y)=H''(y)=0 and build surface in parametrical space with respect to such solutions. Straightforward method leads to 'Warning, solutions may have been lost' for solve command. How to reformulate problem to become it solvable?

I have defined a function 'A' and written a procedure to evaluate it for various variables, as follows:

A := r*sin(m);

Aval := proc (r, m)

evalf(A);

end proc;

Aval(1, Pi);

The function defined by its variables is returned:  r*sin(m).

How can I get maple to return the numerical value of the function?

Hi!

I have the same problem.

   "Simulation problem: maximum number of event iterations reached (100) at t= ...."

I have a model which worked without problem in maplesim2, using a lot of event iterations. The model can only work this way, becouse its a mechanic model where the friction is function of the sliding speed, thus where the speed changes value, the friction coefficient does also, and an event occurs.

I really need to know where...

Hello,

I have got a problem using LPSolve with the option "method=interiorpoint". If I do not add this option it works fine but if I add this option I get the message "Error, (in Optimization:-LPSolve) unrecognized storage format, storage = []"

Could you please help me to deal with that? Thank you.

opoly := (1-x^2)*diff(f(x), x$2) - x*diff(f(x), x) + n^2*f(x) = 0;
sol := op(2,dsolve(opoly));
gen := sum(cos(n*arcsin(x))*y^n/n!, n=0..7);

with(gfun):
seriestoratpoly(series(gen, z, 8), ['egf']);

error not a series, why?

seriestoratpoly(gen, ['egf']);

refere to the following link, it is possible to use a few terms to calculate a generating function, but where is the function generating? how do it  work in gfun?

Hi,

How to solve this equation?

Any Idea?

Thx

Hello!

 I'm new to maple and I'm having some difficulties with coding.

I'll explain the problem

I have 2 vectors, a1 and a2, and I want to make a new set of vectors R(n,m) where R(n,m) = n*a1+m*a2 for n and m from 1 to 100 (as an example). This will create n*m vectors (in this case 10000) that will be marked as R(0,0), R(1,0), R(0,1), R(1,1), R(2,1), ...

It seems as though this would be simple but I haven't found a way to get the repetition statement ...

Whenever I try to plot a simple/small function in 2d, Maple literally takes forever to calculate it whenever the frame rate is too high.

For instance, the following command (from a tutorial, so it should work):

animate( plot, [exp(-x/5)*sin(x),x=0..t], t=0..20, frames=100 );

Will not compute, unless i change the number of frames to 50 or below.

I tried this on a friends computer (he has a mac, but has way weaker performance) and it worked just fine.

Hi,

I was wondering if it is possible for me to generate plots from command-line Maple. What I need to do is access a linux server remotely via PuTTy and then set Maple running on creating a plot (that takes it a couple of days). Is it possible to do this?

I can't seem to find out how after googling for a while, I was thinking it would be something like "maple <inputfile.mpl> outputfile" on the command-line then I'd just let it go and it...

Hello,

To label plot axes as Greek letters, one should use the "labelfont=[SYMBOL]" parameter, but this option makes both axes in Greek letters. Is it possible to make only the horizontal axe as a Greek letter, while the vertical axe remains as an English word?

Thanks in advance.

I have a procedure, lfGn, with two or three real arguments, and I wish to find the maximum value of the procedure.  I was trying the Optimization package, and found this to be extremely slow.  Optimization was called with the following code: the first few lines just set some variables, for use in the last line, which does the call.

max2lfGn := proc (X::Vector) local a, d, e, f, H, m, s;
e := 10.^(1-floor((1/2)*Digits));
a:= Statistics:-Mean(X);
d := Statistics:-StandardDeviation(X);...
