Scilab Function  tf2ss -  transfer to state-space  
Calling Sequence
- sl=tf2ss(h [,tol])  
Parameters
  - h  
    : rational matrix
  
- tol  
    : may be the constant rtol or the 2 vector [rtol atol]
  
  - rtol  
    :tolerance used when evaluating observability.
  
- atol  
    :absolute tolerance used when evaluating observability.
  
- sl  
    : linear system (syslin list sl=[A,B,C,D(s)])
  
Description
  
    transfer to state-space conversion: 
  
  
    h=C*(s*eye()-A)^-1*B+D(s)
  
  
Examples
s=poly(0,'s');
H=[2/s,(s+1)/(s^2-5)];
Sys=tf2ss(H)
clean(ss2tf(Sys))
