Build the PMFG graph from a similarity matrix

File Information
Description

Calculates the PMFG graph from a matrix of weights W (typically a similarity measure, e.g. correlations)
 PMFG = doPMFG(W) returns the palnar maximally filtered graph (PMFG)
 PMFG is a sparse matrix with PMFG(i,j)=W(i,j) if the edge i-j is present
 and PMFG(i,j)=0 if not
 W must be sparse, real, square and symmetric

Hi Tomaso. Thanks so much for sharing this toolbox. Just had an issue when use it. I have installed all the .m files from the Matlab_BGL package. However, I still couldn't run the pmfg.m function.

It said that matlab_bgl\private\planar_test_mex.mexw64':
Access is denied.

And I'm using the Matlab R2012b version. Do you have any ideas why this happens? Thanks sooo much!
