Brain source localization.
This script performs brain source localization using several gain matrices [2], including FAuSTs, and OMP solver. It reproduces the source localization experiment of [1].
The results are stored in "./output/results_BSL_user.mat". DURATION: Computations should take around 3 minutes.
The MEG gain matrices used are the precomputed ones in "data/faust_MEG_rcg_X.mat" (in the installation directory of the FAuST toolbox)
