Hey,
I'm looking to make an AR (all-pole) filter. I would like to be able to select poles by coordinates, and get the filter coefficients from this. I'm really lost on where to start, and Google haven't gotten me far. Could anyone be so kind to give me some hints on where to start?
P.S. It has to be running automatically, so stuff like fdatool isn't an option.
Cheers!

You can use zp2tf to form the transfer function, numerator and denominator, from the zeros, poles, and gains.
