lti/exp - Create pure continuous-time delays
Syntax
Description
d = exp(tau, s)
creates pure continuous-time delays. The transfer function
of a pure delay tau is
d(s) = exp(-tau*s)
You can specify this transfer function using exp.
s = zpk('s')
d = exp(-tau*s)
More generally, given a 2D array M,
s = zpk('s')
D = exp(-M*s)
creates an array D of pure delays where
D(i,j) = exp(-M(i,j)*s)
All entries of M should be non negative for
causality.
