Please, consider this example:

I wonder why the match function returns TRUE and expressions that depend on the main variable x. I hope that someone can give me an explanation.

Best, Henning

I have simulated 50 trajectories of an ODE system, with  a command roughly like this:

myPlot :=
 seq( plots:-odeplot
    ( Sol(i)
    , [ u(t), r(t), q(t) ]
    , t = T .. 0                          ### Time Run Backwards
    , 'numpoints' = 2*abs(T)
    )

Maple 15, Windows7x64, Standard v. Classic

I have noticed that, on my system, the smoothness of some INLINE plots is better in Classic than in Standard. Is this some regression or some installation-specific quirck I wonder?

In Tools->Options, I have plot anti-aliasing enabled (whatever that is).

This looks alright in Classic

plots:-implicitplot(
  [ x^2 + y^2 = 1, x^2 + y^2 = 2 ]
  , x = -2 .. 2
  , y = -2 .. 2

I need to solve an optimization problem. Please offer your insights.

Suppose there are two functions (my case is more complicated than this example).

f(x,y)=x-y, 0<x<1, 0<y<1

g(x,y)=x*y, 0<x<1, 0<y<1

The goal is to get the maximum values for f(x,y) and g(x,y). However, it is not simultaneous, but sequential. In the first stage, only x can be chosen to maximize f(x,y); in the second stage only y can be chosen to maximize g(x,y...

Hi,

I have n second order differential algebriac equations (symbolic). I need to convert this system to [A]{X''} + [B]{X'} + [C]{x} + D =0,  where X is the column vector containg the variables and A,B,C,D are the coefficent matrices of X'', X',X and the constant term matrix respectively.

Is there a way to generate this matrices in Maple?

Thanks.

Giving a expression as follows, how to extract  powers of g to a list?

 In this example the list of powers of g is {2,1,2}

Hi all,

      i am new to maple before getting this software i need to know how it works in order know that i want trial version of maple software how to get this trial version please suggest me some idea...

I have one 2d and one 3d animation that I want to play at the same time.

p1:=animate(sphereplot, [exp(6*sin(t))-1, theta=0..2*Pi, phi=0..Pi], t=0..3, frames=100):
p2:=animatecurve(rhs(sDE), t=0..3, frames=100):
display({p1, p2});
Error, (in plots:-display) cannot display 2-D and 3-D plots together

I also tried using:

p2:=animate(implicitplot,[(i)^2 + (j)^2= (rhs(EQ2))^2,
                               i = -exp(6)..exp(6),
                               j = -exp(6...

I've just registered my copy of maple and I'm trying to figure out how to use it to find the arc length of a curve on a given integral. My function is: upper limit 0, lower limit -3; and after the integral sign, the square root of 1+4x^2 dx.

Hi,

I have a pretty simple problem. Given the following set of responses to a "yes (y)/no (n)" question, create a pie chart and a bar chart.

y, y, n, n, n, y, y, n, n, n, y, y 

I would like solution that does not involve coding the data, say y = 1 and n = 0. I am aware of the BarChart and ColumnChart commands in the Statistics package, but I can't seem to get them to work with nonnumeric data. Is there an easy way to do this?

The folks at Grand Valley State University have posted a nice set of Maple tutorial videos on YouTube.  The videos have been designed for students taking 200-level math courses, but they are certainly suitable for anyone who is either new to Maple, or looking for a refresher.

Enjoy!

Hi,

Is there any  function  in maple to compute the SVD of a matrix  using jacobi method? Or anybody has maple code to do so?

b) Define a procedure f(x, y) which returns −1 if x < y and 1 if

Hi friends,

I am running an application which consumes big memory and the result was given smoothly 

but after 5 hours I running the program again but in the middle of calculation the maple give message show  I got this error:

Execution stopped: Memory allocation failed! Please see 

Hi,

I am currently writing a Python program which takes a Maple Worksheet and evaluate the commands in the terminal version of Maple. However, I have trouble figuring out how the input is formatted. As an example I have following XML code in a .mw file:

<Input><Text-field prompt="&gt; " style="Maple Input" layout="Normal">
<Equation executable="true" style="2D Input" input-equation="A := 4;" 
display="LUklbXJvd0c2Iy9JK21vZHVsZW5hbWVHNiJJLFR5cGVzZXR0aW5n\
