output = SPDToMetSPD(input,T,B)

Convert spectral power distribution
to another metameric spectral power distribution.

output - metameric spectral power distribution
(number-of-wavelengths by number-of-lights)
input - source spectral power distribution
(number-of-wavelengths by number-of-lights)
T - source color matching functions
(n-chromacy by number-of-wavelengths)
B - linear model for spectral power distributions
(number-of-wavelengths by at least n-chromacy)
