Arguments The input arguments sys1,..., sysN can be LTI models of any type. Regular
matrices are also accepted as a representation of static gains, but there should
be at least one LTI object in the input list. The LTI models should be either all
continuous, or all discrete with the same sampletime.Whenappending models
of differenttypes,the resulting type is determinedby the precedence rules(see
Precedence Rules for details).
There is no limitation on the number of inputs.
Example The commands
sys1 = tf(1,[1 0])
sys2 = ss(1,2,3,4)
sys = append(sys1,10,sys2)
produce the state-space model
