Finding transfer function from pole-zero

I have my poles and zeros set as below. I wanted to find the transfer function but i could not find a way. Can you help me? The order of my filter is 5 and my cut-offs are pi/5 and pi/4.

zeropoint = [0, 3*pi/20, -3*pi/20, 6*pi/20, -6*pi/20];

poles = [16/20; (16/20)+(1i/5); -(16/20)+(1i/5); (15/20)+(2i/5); (-15/20)+(2i/5)];
