Magnitude and phase response of IIR filter from given transfer function

I am trying to work to obtain a figure from the following transfer function below:

%numerator coefficients

b0 = 0.05634;

b1 = [1 1];

b2 = [1 -1.0166 1];

%denominator coefficients

a1 = [1 -0.683];

a2 = [1 -1.4461 0.7957];

Please help obtain this code as im getting stuck using differenatied between fir and iir filters formula on matlab code

I think you are looking for the freqz function which gives the Magnitude and Phase response of a filter.
