simtransform
Syntax
out = simtransform(sys,X)
Parameter Li st
Inputs: sys Input system. This may be a state-spa ce system, pdm or
constant matrix.
X Similaritytransform. Xmust be invertible
Outputs: out outputsystem - in the same class as the input.
Description
Apply a similarity transform to sys.Ifsysis a matrix or pdm this gives out =
inv(X)*sys*X.IfsysisaDynamic System this transform is applied to the state.
Applying this transform to a transfer function is meaningless as a state matrix has not
been uniquely deļ¬ned. This will return a warning and leave the transfer function
unchanged.
This command will remove the state names as they no longer have any meaning.
Example
sys1 = randsys(3,1,1,{stable})
rifd(sys1)
