Thank you very much. I was going to understand what happen with the matrix and did not understand how to do. But this is easy 
.
So I changed the code and now I have two results:
test-rgb.dat with the old calculation
test-yuv.dat with the new calculation
I think that the new calculation did it not better than the old one if I compare the results.
Does anybody has an idea how to improve the automatic conversion process?
I am looking forward to your idea
