central moments of all orders
mom = cmoment(x, ord) mom = cmoment(x, ord, orientation)
real or complex vector or matrix
positive integer
index of the dimension along which the cmoment is computed. It can be either
"*"
(default), "r"
or
"c"
real or complex scalar or vector
cmoment(x, ord) or cmoment(x, ord, orientation)
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.
