Matlab error in Computing Edge-Betweenness Centrality

[reyhanehnazemian]

Hello
I'm trying to calculate the betweenness centrality for all edges in an adjacency matrix. I download matlabbgl from https://www.cs.purdue.edu/homes/dgleich/packages/matlab_bgl/ that includes betweenness_centrality.m file and unzip it to a directory. Then I open matlab and change directory until I get to the directory where I unzipped matlabbgl.

Well I'm not 100% sure, but I think that this can be my solution. However, I'm still new to matlab and can't get the code running very well. when I call betweenness centrality with a sparse matrix argument in another file and run it, the matlab gives error :

Undefined function 'betweenness_centrality_mex' for input arguments of type 'double'.
Error in betweenness_centrality (line 110)
bc = betweenness_centrality_mex(A,weight_arg);

OS is Windows 7 enterprise 64-bit and Matlab 2013a
Any help is highly appreciated. I'm currently writing my thesis and desperately need betweenness for my network :) Thanks a lot!!!

That means it can't find the mex files.

Try the files here.

(This may take a few mins to become available...)

Hi David,
I had the same problem, and I tried using the files at the link you posted but it doesn't work for me. I'm running Mac OS 10.12.6 (Sierra) and Matlab 2017b. I get the same error message - Undefined function or variable 'betweenness_centrality_mex'.
Your help would be much appreciated!

I'm gonna try and track down the most recent version of Matlab to check this one out.

If you could compile another mex file and let me know what filename it compiles to, that'd be super helpful!
