Accessing the final conditions (states) of a 'dsp system toolbox' filter

Hi,

I was wondering if there is a way to get the final condition (states) of a dsp filter (e.g., Hd1 = dsp.FIRFilter)?

If I use

d = fdesign.lowpass;
Hd2 = design(d, 'equiripple');

then, I can get the states by typing

states = Hd2.States;

Is it possible to get the states for Hd1?

Thanks, Avihay
