Re: Trouble installing control toolbox

[Michael Noone]

Thanks Marco! I tried doing as you suggested, but am still having troubles.

See below:

octave:11> pkg load control
octave:12> pkg describe control
---
Package name:
        control
Version:
        2.3.52
Short description:
        Octave control systems package based on the proven SLICOT library
Status:
        Loaded
octave:13> L = tf2sys(3e4 * [0.0025 0.1 1], [0.01 1.03 3.03 3.01 1]);
error: `tf2sys' undefined near line 13 column 5
octave:13>

This line is stolen from this page: http://web.mit.edu/6.302/www/compare/report.html

Any ideas what I'm doing wrong now?

Hi - I'm very new to Octave. I'm trying to run it from within Cygwin
(freshly installed) on a 64 bit Windows 7 machine.

I installed Octave as well as octave-forge when installing Cygwin, using
the Cywgin installer. This did not seem to give me the controls toolbox
as I expected (at least as far as I can tell), as running commands like
bode() would give me error messages about undefined functions.

Michael,

the octave-forge packages need to be loaded before use.

octave:2> pkg load control

octave:3> pkg describe  control

Package name:
        control
Version:
        2.3.52

        Loaded

So, I downloaded the control toolbox from here:
http://octave.sourceforge.net/control/ and attempted to install it. See
below:

octave:9> pkg install control-2.4.1.tar.gz

this is for building and installing from source.

Can anybody suggest to me what I am doing wrong?

Thanks so much!!

Regards
Marco
