Nearest-Neighbour energy in periodic boundary conditions in 1D

Share:

Description

Given a vector of flip sites, 1s or -1s, representing up and down spins respectively, return nearest neighbour energy, applying periodic boundary conditions, i.e., cyclic. This function is a pure R implementation.

Usage

1

Arguments

x
