If x is a vector, compute the p-th moment of x.
If x is a matrix, return the row vector containing the p-th moment of each column.
With the optional string opt, the kind of moment to be computed can be specified. If opt contains
"c"
or"a"
, central and/or absolute moments are returned. For example,moment (x, 3, "ac")computes the third central absolute moment of x.
If the optional argument dim is supplied, work along dimension dim.
