For a given gaussian laser beam injected in a multimode fiber optic with a lens, calculates the fiber position and the coupling efficiency as functions of the wavelength, the incident beam waist position and radius, the M square factor, the effective back focal length of the lens, the diameter and numerical aperture of the fiber optic and its entrance facet transmission. The fiber entrance is supposed to be located at the waist of the transmitted beam. For this reason, the calculation is not processed if the transmitted beam waist is "virtual" and not "real"
