Purpose Series connection of two LTI models
Syntax sys = series(sys1,sys2)
sys = series(sys1,sys2,outputs1,inputs2)
Description series connects two LTI models in series. This function accepts any type of
LTI model. The two systems must be either both continuous or both discrete
with identical sample time. Static gains are neutral and can be specified as
regular matrices.
sys = series(sys1,sys2) forms the basic series connection shown below.
This command is equivalent to the direct multiplication
sys = sys2 * sys1
See Multiplication for details on multiplication of LTI models.
sys = series(sys1,sys2,outputs1,inputs2) forms the more general series
connection.
