Design IIR filter from absorption data

Hello!
As the title says, and I have got the coefficients. This:
f = [125 250 500 1000 2000 4000];
alpha = [0.09 0.2 0.5 0.7 0.8 0.9];
N = 1; % Filter order
Fs = 44100 % Sampling frequency
w = f/fs*2*pi; % Frequency in radians
R = sqrt(1-alpha);
% Find R(z) coefficients:
[b,a] = invfreqz(R,w,N,N);
How do I go about from here, as I need to visualize the filter, e.g. a plot of the magnitude response?
Best regards,
Marius
