dscr

dscr — discretization of linear system

Calling sequence

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

`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

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.
