Dear all

I am trying to use glasso for matlab, downloaded from: http://www-stat.stanford.edu/~tibs/glasso/ . I unzipped the file, set the matlab path to the unzipped file and tried to run the function GraphicalLasso.m from the command window, where I got the following error message: ??? Error using ==> glasso at 68 mex file absent, type 'mex glasso.F' to compile

I typed mex glasso.F to the command window and a second error message appeared: >> mex glasso.F

C:\PROGRA~1\MATLAB\R2010A\BIN\MEX.PL: Error: 'glasso.F' not found.

??? Error using ==> mex at 222 Unable to complete successfully.

The same error appears when I try >> mex glasso instead of >> mex glasso.F

I am using MATLABR2010a on a windows 32 bit machine. Any suggestions? (I have already contacted the code author but he didn't reply, yet). Thanks in advance.

Did you cd into the directory where the file exists?

No I didn't. After your comment I changed the current folder to the file where glasso.F is located and I got the following error:

>> mex glasso.F lcc preprocessor error: glasso.F:58 Could not find include file "fintrf.h"

Do you have a Fortran compiler installed? LCC is a C-compiler, which cannot compiler .F files.

Thank you, Jan and James for your comments. I spent the last couple of hours searching for compilers and stuff in the web and from what I understand there isn't any, free of charge, fortran compiler supported by matlab. Am I correct? If I am not, please elaborate!
