Hey Fabs, I got problems with my filter design.  I have a 13-order
Butterworth low-pass with polynomials that are driving me nuts.
Would you happen to have something up your sleeve for this?

Oh, by the way, I hear that you now got stalkers on your tail.
LOL!  Even paradise has its black flies.

If it is a real circuit, then Spice, if it is just polynomials, then
Mathcad.

Or you could spend all your time writting something custom for this
one problem using polynomial libraries.

If you have a 13th order Butterworth there is no question you have 
problems with your filter design.
