Help text

IMPINVAR  Impulse invariance method for analog to digital filter conversion.
	[BZ,AZ] = IMPINVAR(B,A,Fs) creates a digital filter with numerator
	and denominator coefficients BZ and AZ respectively whose impulse 
	response is equal to the impulse response of the analog filter with 
	coefficients B and A sampled at a frequency of Fs Hertz.

	If you don't specify Fs, it defaults to 1 Hz.
