REMEZ            Scilab Group            Scilab Function              REMEZ
NAME
   remez - Remez's algorithm
  
CALLING SEQUENCE
 [an]=remez(nc,fg,ds,wt)
PARAMETERS
 nc   : integer, number of cosine functions
      
 fg,ds,wt
       : real vectors
      
 fg   : grid of frequency points in [0,.5)
      
 ds   : desired magnitude on grid fg
      
 wt   : weighting function on error on grid fg
      
DESCRIPTION
   minimax approximation of a frequency domain magnitude response. The
  approximation takes the form
  
  h = sum[a(n)*cos(wn)]
   for n=0,1,...,nc. An FIR, linear-phase filter can be obtained from the
  the output of remez by using the following commands:
  
                  hn(1nc-1)=an(nc-12)/2;
                  hn(nc)=an(1);
                  hn(nc+12*nc-1)=an(2nc)/2;
   where an = cosine filter coefficients
