Guido Nolte's code for eLoreta (inverse/private/mkfilt_eloreta_v2.m). The main ones are: * The matrix M in line 52 is calculated using the inverse instead of the pseudo-inverse. Pascual-Marqui states in arXiv 0710.3341 equation 44 that the pseudo-inverse should be used here. * The exit condition of the iterative method in line 62 compares the matrix W with the matrix one iteration before. However, as the old W matrix is updated every dipole calculation, the matrix is comparing almost with itself (except for the last dipole). The update of Wold should be taken out of the loop.
