syssize size of state-space system

## Syntax

    [r, nx] = syssize(Sl)

## Arguments

Sl

  linear system (`syslin` list) in state-space

r

  1 x 2 real vector

nx

  integer

## Description

returns in `r` the vector [number of outputs, number of inputs] of the linear system `Sl`. `nx` is the number of states of `Sl`.
