I hope this finds you well. Actually, I've been reading through the file create_network.m from matlab tool WDM and I'm trying to create a network but I always get the same error. Here are the steps I follow and the error.

PS: I tried this also with name: 'mesh.mat' after loading the mesh.mat to working memory. I tried other names as well but I always get the same problem.

create_network(9,'mesh') Does network have wages (y/n): n

Error in ==> create_network>save_network at 161 save(name,'description','structure');

Would you please guide me solve this problem?

  • You do not have write permissions in the directory where you're trying to save. what does `pwd` return? – Oleg Apr 18 '13 at 17:23
  • it gives: C:\Program Files\MATLAB\R2010a\work\networks – user2277784 Apr 18 '13 at 18:03
  • Have you considered moving the WDM toolbox somewhere into another folder but outside the $matlabroot$ where you have write permissions? – Oleg Apr 18 '13 at 18:14
  • Hi @OlegKomarov :) I solved the issue. It was because I forgot to change the path in create_network.mat file. Now it's working perfectly – user2277784 Apr 18 '13 at 19:25
