I am recently new to maple software, but I was wondering if someone was able to help me with the following question.

 

I am trying to plot a 3D graph of some function f(x,y,z), I want a contour type-graph with normal axis, and I also have a few points that I want to plot on that graph:  [x1,y1,z1], ... [xn,yn,zn]; how do I do this on a single graph?

 

thanks so much;

I'm not sure if this happens in Maple 13 and up. But in the standard interface, if you hold your cursor over the maple tab at the bottom of Windows or the maple help tab at the bottom until the flyout (only takes a half second or so) and leave it, while it is there your typing in Maple will lag. Just checked the classic interface and it is not affected by this. Can anyone check this in Maple 13 and 14?

How to change this general form to solve :

How to calculate with Maple Fourier coefficients on some numerical valued functions and how to calculate and plot the 3 partial sums :

 

Function B : on the interval [-phi, phi]

f(x)= NUMERICAL (x – phi/2) + NUMERICAL (x+phi/2)

 

Function C : on the interval [-phi, phi]

f(x) =  NUMERICAL (x+phi/2)

I enclose Maple general solution to the PDF heat equation in 1 dimention.

 

I need corrections of it to enable me to calculate the heat equation in certain conditions :

 du(x,t)/dt - d^2/x,t)/dx^2 = ;   t>0, x belongs to interval [0,phi[

with boundary conditions :

u(x,0) = sin(x)cos^2(x) ; x belongs to interval [0, phi)

u(0,t) = 0

u(phi,t) = 0  ;  t is still t>0

This is in the "Product Suggestions" category since there is no better place to report a bug that I could find.

In Maple 14 using the GraphTheory package on isomorphic (but not identical) transitive 3-regular graphs of order 120,

  IsIsomorphic(G1,G2) hangs.  It seems to do okay if the graphs are not isomorphic (returns false), or if they are identical

  in their labeling (returns true).

A suggestion to fix it would be...

Hi all,

 

I get this strange (to me) behavior:

 

interface(showassumed=0);

assume(theta,real);
assume(phi,real);

SourcePosition:=[phi,theta];

parameters:= [SourcePosition[1],SourcePosition[2]]: 
 save parameters, "./parameter.txt";

wanted_par:=[convert(SourcePosition[1],string),convert(SourcePosition[2],string)]: 
save wanted_par, "./wanted_par.txt";

Hello!

 

I wanted to plot Laplace's spherical harmonics, which basicly worked. But now I wanted to add two sliders with which i want to vary m and l. This also works nearly. I can vary l and plot the new spherical harmonic. The variable m has to hold the restriction: -l<= m < = l.

So my question is, how can i synchronise the two sliders, so that when i edit silder l the range for slider m is changed?

 

Thanks for your help!

I have created a Monte Carlo simulation using maple using the following do loop for each iteration:

 

for count from 1 to n do

...............

end do

 

I would like to show through animation (pointplot) how the model develops with changing n.

 

Can anyone help me with this problem?

 

Thanks in Advance

Hi,

I'm solving a non-linear system of equations (8 equations, 7 parameters) numerically using Fsolve.

Here's my problem: I run fsolve in a loop for different values of one specific parameter. What I would like to do however is have a matrix of parameter values and tell fsolve to pick a new row of that matrix each time as parameter values until it has run down all the rows.

 

I just need some general guidelines and the commands. Much appreciate the help...

Hi,

I was wondering if there is a more elegant way of doing this:

SX := proc ()::set; local j, sx, SEqn; Digits := 30; SEqn := {evalf(subs(EV, Eqn(1)))}; for j from 2 to n do SEqn := `union`(SEqn, {evalf(subs(EV, Eqn(j)))}) end do; sx := SEqn end proc:

thanks :)

Please , can anybody tell me about the basical things to know about Maple that are not described in the internet . I mean about adding a new line with the sign > , joining or parting two parts , or insert a title and above all where i can find the list of the pakages wee need to perform a program .

hi

I have this PDE:

PDE := diff(f(x, y), x, x)+diff(f(x, y), y, y) = 0

With BCs

bc := {f(0, y) = 0, f(1, y) = 0, f(x, 0) = 0, f(x, 1) = sin(Pi*x)}

which has a relatively simple exact solution.

I'm trying pdsolve and getting nowhere, either numerically or symbolically.

Any advice most welcome

thanks

Hello there I'm a newbie, both here and to Maple !

I am performing arithmetic operations with polynomials. Can I get a step by step solution with such operations?
