INVLIB::InvRapMusic implements the RAP-MUSIC scanning algorithm of Mosher & Leahy, IEEE Trans. Signal Process. 47(2), 332-340 (1999). The algorithm decomposes the measurement covariance to obtain the signal subspace, scans the leadfield for the grid-point pair with the largest subspace-correlation, projects that pair out of the signal subspace, and repeats until the desired number of sources is found or the correlation drops below the user-supplied threshold. Outputs are returned as both an InvSourceEstimate (dense grid with active vertices populated) and a list of InvDipolePair records carrying per-iteration orientation and correlation diagnostics.
