## Question about IIR-filters in MATLAB (initial/final conditions)

Hello, When using the function [y,s]=filter(b,a,x,s) in MATLAB and b=1 and a=[0.5 0.5] we have a filter with infinite impulse response. Why does MATLAB operate with the convention that the length of the transient s is max(length(b),length(a))-1 ? Is there something magical about this ? In theory the response is infinite, so the length of the transient could also be 10, 20 or 100 or someth...

Hello, I was wondering if it's possible to interface the EZ-kit ADSP21364 with MATLAB ? I have a program running on the board which collects audio samples and put them in a frame and then calculates the power spectrum based on the contents of the frame. I would like to monitor this power spectrum in MATLAB while the program is running. Is that possible?
