dscr - discretization of linear system

### Sequence d'appel

  `[sld [,r]]=dscr(sl,dt [,m])`

### Parametres

- `sl` : `syslin` list containing `[A,B,C,D]`.
- `dt` : real number, sampling period
- `m` : covariance of the input noise (continuous time)(default value=0)
- `r` : covariance of the output noise (discrete time) given if `m` is given as input
- `sld` : sampled (discrete-time) linear system, `syslin` list

### Description

Discretization of linear system. `sl` is a continuous-time system:

`dx/dt=A*x+B*u (+ noise)`.

`sld` is the discrete-time system obtained by sampling `sl` with the sampling period `dt`.

### Exemples

    s=poly(0,'s');
    Sys=syslin('c',[1,1/(s+1);2*s/(s^2+2),1/s])
    ss2tf(dscr(tf2ss(Sys),0.1))
