Starting in R2016b, instead of using the
step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example,
y = step(obj,x) and
y = obj(x) perform equivalent operations.
Y = step(H,X) computes
the analytic signal,
Y, of the M-by-N input
X, according to the equation
where j is
the imaginary unit and denotes
the Hilbert transform.
Each of the N columns in
X contains M sequential
time samples from an independent channel. The method computes the
analytic signal for each channel.
H specifies the System object on which
to run this
The object performs an initialization the first time the
is executed. This initialization locks nontunable
properties and input specifications, such as dimensions, complexity,
and data type of the input data. If you change a nontunable property
or an input specification, the System object issues an error.
To change nontunable properties or inputs, you must first call the
to unlock the object.
