Path: Thermal/ThermalAnalysis
% Compute the temperature and input flux for the spacecraft components.
This computes the average temperature of each component. The optical
input is a flux vector with magnitude in watts. The planet albedo and
radiation fluxes will be computed from the position r.
The number of points generated will equal the length of the longest
transformation matrix in g or the longest member of e.
If the number of points is > 1 all other members of e and transformation
matrices in g must equal that number of 1.
The computations can use shadowing. To get shadowing you must enter the
shadow and scanLines fields.
