Ratio of vertical to horizontal linear polarization components of a field
p = polratio(fv) returns the ratio of the vertical to horizontal component of the field or set of fields contained in fv.
Each column of fv contains the linear polarization components of a field in the form [Eh;Ev], where Eh and Ev are the field's linear horizontal and vertical polarization components. The expression of a field in terms of a two-row vector of linear polarization components is called the Jones vector formalism. The argument fv can refer to either the electric or magnetic part of an electromagnetic wave.
Each entry in p contains the ratio Ev/Eh of the components of fv.
