 +  <a href=/​reference/​ft_headmodel_halfspace><​font color=green>​FT_HEADMODEL_HALFSPACE</​font></​a>​ 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)
