[Scilab-users] bug in function iir ?

[grivet]

I appreciate your help; however, neither suggestion works: I still get 
the same error message.
The similar line
         [frq,repf]=repfreq(hz,0.01,0.49);
has no problem
> Your problem arises because one frequency value you ask for  
> corresponds exactly to a zero of hz.num
> log(roots(hz.num))/(2*%pi)
> so you want to compute the gain in dB of a zero value which is -inf
>
> To avoid such problem you can let repfreq to do the frequency 
> discretization.
> [frq,repf]=repfreq <repfreq.html>(hz) or equivalently 
> [frq,repf]=repfreq <repfreq.html>(hz,0,0.5)
> in  this case the discretization uses  varying  frequency step
