I am designing fixed-point filters with the Filter Design Toolbox 3.0 (R14), and the LIMITCYCLE function does not work for the DFILT objects that I am supposed to be using with the Filter Design Toolbox 3.0 (R14). I tried using it with a DFILT.DF2SOS object and received the following error:
??? Function 'limitcycle' is not defined for values of class 'dfilt.df2sos'.
