1.Go to the mmed-release-0.1/src/.
That means in a shell you should change directory (cd mmed-release-01/src/) to the mentioned directory. That might be in a folder created, when you unpacked the archive that contained Matlab.
2.Modify the makefile to set appropriate PATHs for Vlfeat, Cplex, GSL Cblas.
In a file called "Makefile" in the directory mmed-release-0.1/src/ there should be variables that contain the location of the libraries "Vlfeat", "Cples", and "GSL Cblas". Since Matlab doesn't know how your system is configured you might have to set those library paths yourself. However you can install them with the Ubuntu package manager and then the linker should normally know where they are.
3.To compile, type: make
In a shell (e.g. gnome-terminal) cd into the directory where the Makefile is located and execute make by typing "make" and pressing enter.
Compiled mex files are put in ./bin/
The result of make can then be found in the subdirectory called bin of the directory where the Makefile is located.
1.Compile LibSVM by going to the source directory and type: make
Change directory to the root of the "LibSVM" library and make it as in the above step 3.
2.Open Matlab, change directory to: ./src/.
Really self explanatory.
3.Change the paths to HMMall and LibSVM, and run: m_setup
That one I don't really get. Either you have to run the script m_setup in Shell or in Matlab. I assume, just like in the Makefile you have to change the respective paths in the file m_setup to the right location of the libraries "HMMall" and "LibSVM"
