eqfir - minimax approximation of FIR filter

### Sequence d'appel

  `[hn]=eqfir(nf,bedge,des,wate)`

### Parametres

- `nf` : number of output filter points desired
- `bedge` : Mx2 matrix giving a pair of edges for each band
- `des` : M-vector giving desired magnitude for each band
- `wate` : M-vector giving relative weight of error in each band
- `hn` : output of linear-phase FIR filter coefficients

### Description

Minimax approximation of multi-band, linear phase, FIR filter

### Exemples

    hn=eqfir(33,[0 .2;.25 .35;.4 .5],[0 1 0],[1 1 1]);
    [hm,fr]=frmag(hn,256);
    plot(fr,hm),
