Z-transform
ztrans(
finds the Z-Transform of
f
)f
. By default, the independent variable is
n
and the transformation variable is z
. If
f
does not contain n
,
ztrans
uses symvar
.
If any argument is an array, then ztrans
acts
element-wise on all elements of the array.
If the first argument contains a symbolic function, then the second argument must be a scalar.
To compute the inverse Z-transform, use iztrans
.
