I have this result :

There should be three Lab numbers on the third line but only L and a are showing, with two decimals of precision each (50.91 -46.21 ,). I have not completely figured out how to control the num2str conversion, the best I had was this :
Line1 = ['(X,Y) = ', num2str(posX), ', ', num2str(posY)];
Line2 = ['RGB = ', num2str(RGB(1,1,1)), ', ', num2str(RGB(1,1,2)), ' , ', num2str(RGB(1,1,3))];
Line3 = ['Lab = ', num2str(Lab(1,1,1),2), ', ', num2str(Lab(1,1,2),2), ' , ', num2str(Lab(1,1,3),2)];
Line4 = ['Lch = ', num2str(Lab(1,1,1),2), ', ', num2str(chroma,2), ' , ', num2str(hueAngle,3), '°'];
I have not figured out yet the proper parameters to get a conversion from double to string with no decimal part?
