tf2ss

transfer to state-space

Calling Sequence

sl=tf2ss(h [,tol])

Arguments

: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))
