Determine whether an LTI model is continuous or discrete

Syntax

Description

boo = isct(sys) returns 1 (true) if the LTI model sys is continuous and 0 (false) otherwise. sys is continuous if its sample time is zero, that is, sys.Ts=0.

boo = isdt(sys) returns 1 (true) if sys is discrete and 0 (false) otherwise. Discrete-time LTI models have a nonzero sample time, except for empty models and static gains, which are regarded as either continuous or discrete as long as their sample time is not explicitly set to a nonzero value. Thus both

are true. However, if you explicitly label a gain as discrete, for example, by typing

isct(g) now returns false and only isdt(g) is true.
