Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_headmodel_halfspace”.

FT_HEADMODEL_HALFSPACE creates an EEG volume conduction model that is described with an infinite conductive halfspace. You can think of this as a plane with on one side a infinite mass of conductive material (e.g. water) and on the other side non-conductive material (e.g. air). Use as headmodel = ft_headmodel_halfspace(mesh, Pc, ...) where mesh.pos = Nx3 vector specifying N points through which a plane is fitted Pc = 1x3 vector specifying the spatial position of a point lying in the conductive halfspace (this determines the plane normal's direction) Additional optional arguments should be specified as key-value pairs and can include 'sourcemodel' = string, 'monopole' or 'dipole' (default = 'dipole') 'conductivity' = number, conductivity value of the conductive halfspace (default = 1) See also FT_PREPARE_VOL_SENS, FT_COMPUTE_LEADFIELD
