## Name

dscr — discretization of linear system

## Calling Sequence

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

## Parameters

- 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`

.

## Examples

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