This is a goal I do understand.

I don't get yet the point.  Please explain what you would like to achieve
in detail.

That is for filter synthesis right?

And you coded it in Octave?

Now you want it have run from within the Qucs filter synthesis program.
Did I understand that correctly?

BTW: Vincent already made some more efforts regarding filter code.  He
added odd Cauer, zig-zag, and chebychev 2 (inverse) filters to his code
and we are right now figuring out how to use his code...  Right, Vincent?

So what will your code be about?

The only thing I saw in this proposed lib was some numerial functions, so
actually there seems no reason to use these if you intend to use GSL
anyway?

I do not yet see the purpose of this library yet.  Please explain.

Cheers, Stefan.
