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.
