% Computes the ray transfer matrix from a lens file or table.
The distance from the optical axis is the distance on entry to the
optical system, i.e. at the first element.
Type RayTransferMatrixFromLensFile for a double Gauss lens demo.
--------------------------------------------------------------------------
Form:
[mT, xT] = RayTransferMatrixFromLensFile( l, x, nA )
--------------------------------------------------------------------------
------
Inputs

.vNo (1,1) Abbe V-number, the reciprocal of the
relative dispersion of the material
.sa (1,1) Semi aperture
x (2,:) Rays [distance from optical axis;angle]
nA (1,1) Ambient index of refraction
-------
Outputs
