zpell            Scilab Group            Scilab Function              zpell
NAME
   zpell - lowpass elliptic filter
  
CALLING SEQUENCE
 [zeros,poles,gain]=zpell(epsilon,A,omegac,omegar)
PARAMETERS
 epsilon    : real : ripple of filter in pass band (0<epsilon<1)
            
 A          : real : attenuation of filter in stop band (A>1)
            
 omegac     : real : pass band cut-off frequency in Hertz
            
 omegar     : real : stop band cut-off frequency in Hertz
            
 zeros      : resulting zeros of filter
            
 poles      : resulting poles of filter
            
 gain       : resulting gain of filter
            
DESCRIPTION
