Central moment

Calculate the central moment of a given order

The central moment of order k of the selected signal is computed, i.e. the expression

where

is the mean value of the signal.
The central moment value is then displayed in the message window or a text box.

Parameters are

order k of the moment and
output, which determines whether the central moment is to be displayed in
- a "Text box" (0) or
- the "Message window" (1)

CentralMoment(x,k,output); signal x; int k; option output;
