hii all...
i am trying to write C++ code for the filter function in matlab.
(y=filter(b,a,x))..can any one tell me wat the filter function in
matlab actually does...(the steps involved in filtering the data x
using the filter coefficients a and b)..since its an inbuilt function
the matlab code for it is not available .
