Doubt in implementation of linear phase iir filter

Started by sham ganth September 15, 2003
Sir,
Iam trying to implement Linear phase IIR filter in Matlab. Iam a
Post Graduation Student from South india. I need your help. My basic
refrence is "A technique to realize linear phase iir filter" by
Powell and Chou. IEEE signal processing paper. Iam having doubt in
implementation of the system in matlab. I have a IIR filter in my
system and iam trying to reset the state variables of that filter. Is
their any command in matlab or what step i have to follow to do this.
If anyone came across linear phase iir filter please say the website
which i have to see for the details.
Thanks in advance,
