Maple doesn't recognize 'complexplot3d'...

I'm new here, so I'm not totally sure this is the right place to ask this. I apologize if it isn't, please let me know in that case.

My problem is that Maple won't recognize the built-in command 'complexplot3d'. For example, typing:

complexplot3d(z^2, z = -1-I .. 1+I)

doesn't do anything, and it's displayed again in blue as if it was not a command.

Any kind of help would be extremely helpful, as I have no clue of what's going on. Thanks in advance!

Plotting Szego curve...

I want to plot a curve of the form |z*e^(1-z)| = 1 (the Szego curve). I am not sure how to call complexplot() to make this happen. Just calling complexplot(abs(z*exp(1-z)) = 1) does not work, and I don't know what else to specify. Any help?

Trouble plotting complex equation....

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct

For the life of me I can not get maple to plot this equation.  I have poured over various resources and it simply isn't working.  I have gone so far as to use SIMPLIFY and even  Re(circuitSix) and Im(circuitSix) yet still get only errors.  Any insight would be appreciated.

Graph for stability analysis...

can anybody help me..? why my graph not come out? Is that any mistake in my coding?

stability of the scheme...

i want to plot the graph based on this equation to know the stability of this equation :

y := A*(1/x+x*exp(-2*sqrt(-1)*b))+4*sin(h)^2*(2*exp(-sqrt(-1)*b)-3*sin(h)^2*x^(-sin(h))*exp(sqrt(-1)*b*(-sin(h)-1))+3*x^(-sin(h))*exp(sqrt(-1)*b*(-sin(h)-1)))/(3*(1-r))-exp(-2*sqrt(-1)*b)/x-x;

with A = (1+r)/(1-r), r = (1/3)*sin(h)^2, b = m*Pi*h, m = 1, h=0.05

can somebody help me..??

Some problems with compexplot...

Help me with this:

I have a differential equation:  s:= diff(h(t),t) = -0.1738137398e-2/sqrt(2.8-h(t))

Solution is: h(t) = 14/5-(1/100000000)*2607206097^(2/3)*t^(2/3), h(t) = 14/5-(1/100000000)*(-(1/2)*2607206097^(1/3)*t^(1/3)-(1/2*I)*sqrt(3)*2607206097^(1/3)*t^(1/3))^2, h(t) = 14/5-(1/100000000)*(-(1/2)*2607206097^(1/3)*t^(1/3)+(1/2*I)*sqrt(3)*2607206097^(1/3)*t^(1/3))^2

And i have to need a plot... so i use complexplot and recive a mesage:

Error, (in plots:-complexplot) invalid input: `plots/complexplot` expects its 2nd argument, r, to be of type {range, name = range}, but received h(t) = 14/5-(1/100000000)*(-(1/2)*2607206097^(1/3)*t^(1/3)-((1/2)*I)*3^(1/2)*2607206097^(1/3)*t^(1/3))^2

Help me if you can!! Thank you so much!!!

Display multiple complexplot...

Hello everyone,

I'm having some trouble overlaying a set of complex plots. I follow the usual procedure 'display(p0,p1)' I only get p1...

If i try with plots the display command works fine, here's the piece of code I'm trying to get working (r is defined elswhere as function of x and phi):

i := 0;

p := Array(0 .. 10);

for x from 0 by .2 to 2

do p[i] := complexplot(r, phi = -(1/2)*Pi .. (1/2)*Pi);

i := i+1

end do;

display(p[1], p[10]);

Any hints?

Cheers,

Felipe

Plotting complex roots of a polynomial...

I've used fsolve in Maple 6 to find the roots (real and complex) of a polynomial.  I'd like to create a plot showing the location of those roots in the complex plane.  How can I do this?

Complex dispersion relation...

I have a problem related to solving the complex equation of dispersion relation.

In the plots some modes are missed. I dont know whay?

Is possible to help me? (m0^2<0).

restart;

m0:=sqrt((c0^2-v^2)*(1-v^2)/((c0^2+1)*(ct^2-v^2)));

Maple

I would like to pay the attention of the MaplePrimes users
to a Robert Chero application.
This is a Maple package on graphics, which can be implemented in Maple as a usual package.
It  has community rating 4.5 stars. This package can be downloaded from http://www.maplesoft.com/applications/view.aspx?SID=1671.
It was submitted in 2005 when MaplePrimes started. Because of this reason this...
