Representation of a Rotation Matrix

  1. Jan 7, 2009 #1
    Okay, since I did not get any feedback on my previous post under Generalized Spin Matrices, perhaps because the question did not give enough background information, I will restate my question in a different form.

    Say I have a matrix similar to the SO(3) matrix for general 3-D rotations, except it has slightly different (simpler) elements, and the symmetry is as follows:

    [tex] \left(\begin{array}{ccc}
    A & B & C \\
    B & D & E \\
    C & E & D
    \end{array}\right) [/tex] ,

    with A, B, C, D, and E all involving somewhat simple terms with sines and cosines of up to 3 angles (i.e. [tex] \sin\theta 12[/tex], [tex]\cos\theta 13[/tex], and [tex]\sin\theta 23 [/tex]). Is it possible to put this matrix into a basis using only 3 independent unit vector matrices? Let me know if you want more info.
