zpch2 - Chebyshev analog filter

### Sequence d'appel

  `[zeros,poles,gain]=zpch2(n,A,omegar)`

### Parametres

- `n` : integer : filter order
- `A` : real : attenuation in stop band (`A>1`)
- `omegar` : real : cut-off frequency in Hertz
- `zeros` : resulting filter zeros
- `poles` : resulting filter poles
- `gain` : Resulting filter gain

### Description

Poles and zeros of a type 2 Chebyshev analog filter gain is the gain of the filter

    H(s)=gain*poly(zeros,'s')/poly(poles,'s')
