Hi All,
I have Octave 3.8 running on a linux 64 bit machine, and
have managed to install SymPy 0.7.4.1.
What is the correct version of the symbolic toolbox for the above
and how do I specify this from the Octave command line when
installing ?
octave:1> pkg install -forge symbolic ?
The above command currently produces the error:
configure: error: SymPy version 0.7.5 or later is required
checking for sort... /usr/bin/sort
checking for GNU coreutils... yes
checking for python... /usr/bin/python
checking python module: sympy... yes
checking for SymPy version... 0.7.4.1
checking for gawk... gawk
pkg: error running the configure script for symbolic.
error: called from 'configure_make' in file
/usr/share/octave/3.8.1/m/pkg/private/configure_make.m near line 72, column 9
error: called from:
error: /usr/share/octave/3.8.1/m/pkg/private/install.m at line 206, column 5
error: /usr/share/octave/3.8.1/m/pkg/pkg.m at line 394, column 9

Thanks.
Regards,
Constantine.

Thanks for the work and the new version!
I have a question: is there a sort of tutorial/manual with some examples for
the commands?
Thanks

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.

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 simple
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.
I see this but I don't see the connection with symbolic. There is the reference
to non-symbolic ezplot3 where I see this
example with no symbolic functions.
OK I get your point!
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 t
t=.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)
This example that I made is actually very bad!!!
This is much better
syms t
x=t**2
y=t
z=cos(t)**2 +sin(t)*cos(t) +t/100
ezplot3(x,y,z,[0 10],55)
the term [0 10] is the range that is used for t
and the 55 is the number of points to make in that range.
