Detailed Description
template<typename TReal>
class aiMatrix3x3t< TReal >
Represents a row-major 3x3 matrix.
There's much confusion about matrix layouts (column vs. row order). This is always a row-major matrix. Not even with the aiProcess_ConvertToLeftHanded flag, which absolutely does not affect matrix order - it just affects the handedness of the coordinate system defined thereby.

template<typename TReal >
A function for creating a rotation matrix that rotates a vector called "from" into another vector called "to".
Input : from[3], to[3] which both must be normalized non-zero vectors Output: mtx[3][3] – a 3x3 matrix in colum-major form Authors: Tomas M�ller, John Hughes "Efficiently Building a Matrix to Rotate One Vector to Another" Journal of Graphics Tools, 4(4):1-4, 1999
template<typename TReal >
Invert the matrix.
If the matrix is not invertible all elements are set to qnan. Beware, use (f != f) to check whether a TReal f is qnan.
