moment
non central moments of all orders
Syntax
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')
