icsignal creates an icsignal object,
which is a symbolic column vector. The icsignal object
is used with iconnect objects to specify signal
constraints described by the interconnection of components.
v = icsignal(n) creates
an icsignal object of vector length n.
The value of n must be a nonnegative integer. icsignal objects
are symbolic column vectors, used in conjunction with iconnect (interconnection)
objects to specify the signal constraints described by an interconnection
v = icsignal(n,name) creates
an icsignal object of dimension n,
with internal name identifier given by the character string argument name.
