tf2ss

transfer to state-space

Syntax

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))
