I see this but I don't see the connection with symbolic. There is the reference to non-symbolic ezplot3 where I see thisAm 27.11.2015 um 16:37 schrieb Doug Stewart:

Doug, thanks, I knew this page already, but for many functions only the definition is given, i.e. h = ezplot3 (f1, f2,f3). Here one has to try out how it works, a simpleAm 27.11.2015 um 16:13 schrieb Doug Stewart:

Thanks for the work and the new version!_______________________________________________Hi everyone
a new release of the symbolic package  is out, version 2.2.3, by
Colin B. Macdonald.
A summary of important user-visible changes is also available online .
The Octave-Forge Symbolic package adds symbolic calculation
features to GNU Octave. These include common Computer Algebra System tools
such as algebraic operations, calculus, equation solving, Fourier and Laplace
transforms, variable precision arithmetic and other features. Internally,
the package uses [SymPy](www.sympy.org), but no knowledge of Python is
required. Compatibility with other symbolic toolboxes is intended.
Enjoy Octave symbolically,
Help-octave mailing list
I have a question: is there a sort of tutorial/manual with some examples for the commands?
I put these there for you to play with.If there are other commands that you want a demo for, just ask here and I will help you if i can!!!
@Karl, was that helpful?
Please help us make the wiki better by giving us feed back.
one-line example to get it working and then to play around would be very helpful. Maybe some people can see it easily how to use these functions, but I often need an example to
get me going.
Thank you Karl.
when I typehelp ezplot3 i see:
-->> help ezplot3'ezplot3' is a function from the file /usr/local/share/octave/4.1.0+/m/plot/draw/ezplot3.m
-- Function File: ezplot3 (FX, FY, FZ)-- Function File: ezplot3 (..., DOM)-- Function File: ezplot3 (..., N)-- Function File: ezplot3 (HAX, ...)-- Function File: H = ezplot3 (...)
Plot a parametrically defined curve in three dimensions.
FX, FY, and FZ are strings, inline functions, or function handleswith one argument defining the function. By default the plot isover the domain '0 <= T <= 2*pi' with 500 points.
If DOM is a two element vector, it represents the minimum andmaximum values of T.
N is a scalar defining the number of points to use in plotting thefunction.
If the first argument HAX is an axes handle, then plot into thisaxis, rather than the current axes returned by 'gca'.
The optional return value H is a graphics handle to the createdplot.
fx = @(t) cos (t);fy = @(t) sin (t);fz = @(t) t;ezplot3 (fx, fy, fz, [0, 10*pi], 100);
See also: plot3, ezplot, ezmesh, ezsurf.
Additional help for built-in functions and operators isavailable in the online version of the manual. Use the command'doc <topic>' to search the manual index.
Help and information about Octave is also available on the WWWmailing list.>>
Do you not see this???
example with no symbolic functions.
I will make a demo. probable take me 2-3hrs as i am doing other things also.
Here is a simple demo I hope it helps.There are other ways to do this --- this is just one try.
syms tt=.1:.01:5;x=function_handle(sym("t**2"))y=function_handle(sym("t/0.33"))z=function_handle(sym("cos(t) +sin(t)*cos(t) +t"))ezplot3(x,y,z)
