Dear Fortran (or even FORTRAN) users, I am attempting to analyse a large complex network. I am interested in various statistics such as the distribution of connections (or edges) between nodes, various centrality measures etc. I wondered if anyone has coded such analysis in Fortran and if so if they might share the implementation. I have been using the program Pajek, which is designed for such analysis. Pajek is oriented more towards graphical analysis, however, and I am more interested in statistical output at this point as my network is dynamic and I am yet sure over what time frame I should define the network. Consequently, I want to be able to modify the program to produce only the statistics in which I am interested for each set of input data. Thank you for your help in advance.
