how do i work out the transfer function of my filter for use in an adaptive filter?

Hey, I just need a bit of help getting to a transfer function for a filter.

i have to use an FIR filter that i designed in an adaptive filter set up and it seems as though i'll need it in transfer function form to do this. How do I get to transfer function form?

Many thanks, Tom

If it's an FIR, then the coefficients are the transfer function. Say the coefficients are stored in b, then you can view the transfer function as

freqz(b,1)
