####################		FAuST Toolbox			##########
##########################################################################


##########################################################################
General purpose:

The FAuST toolbox contains a C++ code implementing a general framework 
designed to factorize matrices of interest into multiple sparse factors. 
It contains a template CPU/GPU C++ code and a Matlab wrapper.
The algorithms implemented here are described in details in [1]- Le Magoarou



For more information on the FAuST Project, please visit the website of the 
project: <http://faust.gforge.inria.fr>

Main tools :

The main functions offered by the FAuST toolbox are implemented in two files
	- hierarchical_fact.m
        [lambda, facts, errors] = hierarchical_fact(params);
        input:
            - params: Structure contained data matrice, desired number 
                      of factors, constraint sets...   
        output: 
            - lambda: multiplicative scalar
            - facts : estimated factorization (cell array of sparse matrices)	
            - errors
	- palm4MSA.m
        [lambda, facts] = palm4MSA(params)
        input:
            - params: Structure contained data matrice, desired number 
                      of factors, constraint sets...
        output:
            - lambda: multiplicative scalar
            - facts : estimated factorization (cell array of sparse matrices)

Demonstration:

This package contains the Matlab code which represented the results of [1].
One demonstration is available in "./misc/demo/" directory: 
-	Source_localization using MEG data (cf. Sec.V. of [1];)

See related ./misc/demo/README file for more detail. 

This package contains a CTest tool to execute binary file automatically.
(cf. CMakeLists.txt)
