NumPy is primarily meant as an N-dimensional array manipulation  
library, so an IIR/FIR filter doesn't really fit into this. The  
developers are not aiming at mimicking Matlab, but are offering NumPy/ 
SciPy as a viable open-source alternative, where SciPy is the package  
to be used for mathematics, science, and engineering.
