Is it possible to generate a histogram based on wavelength (visible light), rather than RGB values? Even if it is a slight approximation, it would be very useful.

Like I said in the link Walter referred you to, Some arbitrary RGB does not necessarily map to one single pure wavelength. A single RGB triplet of values might be arrived at from a whole broad spectrum of wavelengths, not just one wavelength. This is general color science, not something specific to MATLAB.
Not only that but there can be "metamers" - spectra that are completely different but that give the same RGB values. Google metamerism to learn more.
You might be interested in this link or this one or this one.
