Hi Rune, very thanks by the answer, but, the Wikipedia link http://en.wikipedia.org/wiki/Euler's_rotation_theorem does not elucidate the doubt... There are a lot of text and theory there, but, not a numeric or practical example of the type I have shown before ( [ 0.245 0.563 0.055 ]' = R * [ 0.3 0.5 0.2 ]' ) ...
Please, how would you find the R matrix of this problem? The information above is enough to find that ?
Very Thanks,
Carlos Junior carlosjunior@gmail.com
