Returns ------- resmat : array, shape (n_dipoles_lcmv, n_dipoles_fwd) Resolution matrix (filter matrix multiplied to leadfield from forward solution). Numbers of rows (n_dipoles_lcmv) and columns (n_dipoles_fwd) may differ by a factor depending on orientation constraints of filter and forward solution, respectively (e.g. factor 3 for free dipole orientation versus factor 1 for scalar beamformers).
