Adjust the scene wavelength representation

Wavelengths are adjusted by linear interpolation of the spectral radiance data.

Adjust the wavelength to 5 nm spacing

scene = sceneSet(scene,'wave',400:5:700);
scene = sceneSet(scene,'name','5 nm spacing');
ieAddObject(scene); sceneWindow;
fprintf('Note the wavelength representation in the window\n');

Note the wavelength representation in the window

Now get a narrow band representation

scene = sceneSet(scene,'wave',500:2:600);
scene = sceneSet(scene,'name','2 nm narrow band spacing');
ieAddObject(scene); sceneWindow;
fprintf('Note the wavelength representation in the window\n');
