they are not there. There are other filter design methods in that 
kit...kaiser comes to mind and yule-walker come to mind. U should look at

        The signal processing toolbox in matlab represents some pretty 
state of the art stuff, IMHO. I have been making extensive use of it 
lately. I am sure an awful lot of time and money went into those m-files. 

        It would be nice, but it is not reasonable to assume, that Octave 
should have all of those nice tools.

        But somebody is going to have to write them. :-(

        And they cant steal them from matlab either.

        I am sure that somebody will write some someday. It might even 
be me. But it wont be real soon.

                U will probably need to continue to use matlab for those 
functions if they are required for your work, ie if this is for an 
undergraduate signal processing class.

        If u are just trying to make an iir filter with a specific 
specification then look at yule-walker. I just used the matlab version of 
yule walker in my undergraduate signal processing class assignment.
