Prony's method for designing IIR filter response.
[B,A] = prony(H, NB, NA)
Impulse response of filter.
Order of the numerator polynomial.
Order of the denominator polynomial.
Numerator polynomial of order NB+1 of the designed filter.
Denominator polynomial of order NA+1 of the designed filter.
Computes the numerator and the denominator polynomials B and A in z-1 of order NB+1 and NA +1 for a given impulse response H. This function is a clone of MATLAB's prony function and hence gives similar results.
