when I attempt to use the lap_perrin function contained within the EEGLAB laplacian
plugin I receive an error. When matlab attempts to inv(mat) where mat is (i think!) some
form of spline I get a message saying my matrix is badly scaled or singular (and
therefore has no inverse).
Does anyone have any suggestions about what it is in my electrode coordinates that
may cause this to arise?
