Help text

CHEB2AP	Chebyshev type II analog lowpass filter prototype.
	[Z,P,K] = CHEB2AP(N,Rs) returns the zeros, poles, and gain
	of an N-th order normalized prototype type II Chebyshev analog
	lowpass filter with Rs decibels of ripple in the stopband.
	Type II Chebyshev filters are maximally flat in the passband.
