I have magnitude and phase data for given frequencies. I need to find and optimize the parameters of a transfer function with certain poles and zeros. Can someone help with which functions/steps should I use?

Re: Poles an Zeros ... Basically, you can express the behavior of a linear, continuous-time, time-invariant system with a mathematical construct called a "transfer function".... It turns out to be very easy to calculate the response of such a system to a continuous sine wave at a particular frequency -- in this case the poles of a system will tend to make the system gain go down as the frequency is increased, and the zeros will make the gain go up. ...

Re: Warping Pole/Zero Plot ... My plots of the frequency response look correct, but the scaling on the y-axis is not the same. ... I find the poles and zeros of this solving the quadratic equation for the denominator and the a simple algebraic one for the numerator. ... I find a new transfer function from this and plot it. ...
