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)

Parameters

• 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')
