Description of Shift
The unit called Shift performs a cyclic shift by a given number of elements.
The input can be any VectorType
data set, in other words any real or complex one-dimensional data set.
The user chooses the number of elements to shift in the parameter window.
A positive shift means shifting elements to the right (element zero goes
to a higher position and the last elements are wrapped around to the beginning),
while a negative shift means shifting elements to the left (the highest
element goes to a lower position and the first elements are wrapped around
to the end).
Using Shift
Shift's parameter window is shown below.

To choose the number of elements to shift by, move the slider or enter
the number in the box to the right of the slider. The number can be any
integer, positive or negative. The integer can be larger than the size
of the data set: the net shift is just the remainder when this integer
is divided by the length of the data set.
