 Matlab codes for the NonLocalPageRank Algorithm
 
 This repository contains the codes used for generating the examples in the paper : 
-- S. Cipolla, F. Durastante, F. Tudisco. Nonlocal PageRank - [arXiv:2001.10421](https://arxiv.org/abs/2001.10421)
+- S. Cipolla, F. Durastante, F. Tudisco. Nonlocal PageRank - ESAIM: M2AN, Forthcoming article, DOI: [https://doi.org/10.1051/m2an/2020071](https://doi.org/10.1051/m2an/2020071) - [arXiv:2001.10421](https://arxiv.org/abs/2001.10421)
 
 To run the code the implementation of the Power Method from https://www.cs.purdue.edu/homes/dgleich/codes/innout/ is needed.
