# cmoment

central moments of all orders

## Calling Sequence

    mom=cmoment(x,ord)
                mom=cmoment(x,ord,'r') or mom=cmoment(x,ord,1)
                mom=cmoment(x,ord,'c') or mom=cmoment(x,ord,2)

## Arguments

x

  real or complex vector or matrix

ord

  positive integer

## Description

cmoment`(x,ord)` is the central moment or order ord of the elements of `x`. If a third argument of type string `'r'` (or `1`) or `'c'` (or `2`) is used, we get in the first case, a row vector `mom` such that `mom(j)` contains the central moment of order `ord` of the `j` column of `x`. `cmoment(x,ord,'c')` is used in the same way for the central moments in the rows.
