Hi
Do you know why the matrix is not symmetric ?
And why the some of the diagonal values are minus (-)
Hi,
There's no constraint on a 3x3 rotation matrix that forces the components to be positive or that those terms you highlight must be equal:

Under the General Rotation section you can see the format for an arbitrary rotation consisting of a rotation around the 3 principle axes.
