Thank you in advance for your attention.

I guess that my question is quite easy but I just want to make sure that I am right...

I am trying to implement a shelving filter, and I have found a matlab command on the internet which does exactly what I need.

The problem is that my matlab release, 7.12 doesn´t recognize this command and I dont know what´s going on...

I know that other commands such as fdesign generates all kind of filters... but I need to get B and A coefficients of the filter specified.

Regards,

Luis.

Thank you so much Walter,

I didn´t notice that it was a function and I had to download and copy it in my workspace... I guess that it will work
