Application to use SPM ID Toolbox

[Juan Pablo Carbajal]

Dear developers and user,

Please read the following answer from the SPM developer.

@Lukas: I think you work in Mac, right? Can you give him some tips?

We may get a great System Indentification toolbox in Octave! :D

Dear Juan Pablo,

Thanks for your email.

The situation regarding the toolbox has changed since last I wrote - I
am currently actively updating it and in fact just
in the last few weeks was investigating what it would take to make it
run under octave.

A problem here is that I work on a Mac, and the distribution of octave
on that platform does not seem to be so well supported.

To begin with, there is no .pkg or .dmg distribution as for almost all
other mac software - one needs to install fink.

I have done that, but then the octave package management does not seem
to work - attached is a screen grab on my mac
illustrating that I cannot install the control package you mention.

Having said that - I am very interested in making my software
available and working with octave.

Best regards

Brett
