PlanckL:

Path: Thermal/ThermalAnalysis

% Planck's law for a black body.
 Also computes the total flux over the range of wavelengths.

 Type PlanckL for a demo.

   Inputs
   ------
   T            (1,n) Temperature (deg-K)
   lambda       (n,m) Wavelength vector (micro-meters)

   -------
   Outputs
   -------
   q            (n,m) Black body flux density (watts/m^2-microns)
   lambda       (n,m) Wavelength vector (micro-meters)
   qTotal       (n,1) Total flux (watts/m^2)
