iirlp(1) Scilab Function iirlp(1)
NAME
iirlp - Lp IIR filter optimization
CALLING SEQUENCE
[cost,grad,ind]=iirlp(x,ind,p,[flag],lambda,omega,ad,wa,td,wt)
PARAMETERS
x : 1X2 vector of the module and argument of the poles and the
zeros of the filters
flag : string : 'a' for amplitude, 'gd' for group delay; default case
for amplitude and group delay.
omega : frequencies where the filter specifications are given
wa,wt : weighting functions for the amplitude and the group delay
lambda : weighting (with 1-lambda) of the costs ('a' and 'gd' for
getting the global cost.
ad, td : desired amplitude and group delay
cost, grad : criterium and gradient values
DESCRIPTION
optimization of IIR filters for the Lp criterium for the amplitude and/or
the group delay. (Rabiner & Gold pp270-273).
