-   <para>
-[x_r,t_r] = impz(b,a) returns the impulse response of the filter with numerator coefficients, b, and denominator coefficients, a. impz chooses the number of samples and returns the response in the column vector, x_r, and the sample times in the column vector, t_r. t_r = [0:n-1]' and n = length(t) is computed automatically.
