SymIndx: Symmetrizing vector

In MultiStatM: Multivariate Statistical Methods

Symmetrizing vector

Description

Vector symmetrizing a T-product of vectors of the same dimension d. Produces the same results as SymMatr

Usage

SymIndx(x, d, n)

Arguments

x	the vector to be symmetrized of dimension d^n
d	size of the single vectors in the product
n	power of the T-product

Value

A vector with the symmetrized version of x of dimension d^n
