function output = FindModelWeights(input,B)
% output = FindModelWeights(input,B)
%
% Find the linear model weights for a spectral
% power distribution.
%
% INPUT
% input - source spectral power distribution
% (number-of-wavelengths by number-of-lights)
% B - linear model for spectral power distributions
% (number-of-wavelengths by n-dimension)
% OUTPUT
% output - linear model weights
% (n-dimension by number-of-lights)
% We find the weights by linear regression.
output = B \ input;
