# moment

non central moments of all orders

### Calling Sequence

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

### Arguments

x

real or complex vector or matrix

ord

positive integer

### Description

moment`(x,ord)` is the non 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 non central moment of order `ord` of the `j` column of `x`. `moment(x,ord,'c')` is used in the same way for the non central moments in the rows.

### Examples

```x=[0.2113249 0.0002211 0.6653811;0.7560439 0.3303271 0.6283918]
mom=moment(x,3)
mom=moment(x,2,'r')
mom=moment(x,3,'c')```
