append
11-13
Arguments The input arguments sys1,..., sysN can be LTI models of any type. Regular
matrices are also accepted as a representation of static g ains, but there should
be at least one LTI object in the input list. The LTI models should be either all
continuous,or alldiscretewiththesamesampletime. Whenappendingmodels
of different types,the resultingtype is determined by the precedence rules (see
“Precedence Rules” on page 2-5 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)
