             4.8   Implementations and Examples

             4.8.1  Spectral bandpass correction

             The function cband applies the Stearns–Stearns correction method [Equations
             (4.7) and (4.8)] to a reflectance vector.




                Box 1: cband.m

                function [cP] = cband(P)


                % function [cP] = cband(P)
                % applies Stearns-Stearns spectral bandpass correction
                % operates on matrix P of dimensions 1 by n
                % where n is the number of wavelengths
                % returns corrected matrix cP
