Purpose Group LTI models by appending their inputs and outputs
Syntax sys = append(sys1,sys2,...,sysN)
Description append appends the inputs and outputs of the LTI models sys1,...,sysN to form
the augmented model sys depicted below.
For systems with transferfunctions ,..., , the resulting system
sys
has the block-diagonal transfer function
For state-space models
sys1 and sys2 with data
and ,
append(sys1,sys2) produces the following state-space
model.
