Convert a set of rotations to quaternions.

Parameters:

rotarray, shape (…, 3, 3)

The rotation matrices to convert.

tolfloat

Tolerance for the determinant checking that the rotation matrices are valid. The default (1e-3) should be suitable for most cases.

Returns:

quatarray, shape (…, 3)

The q1, q2, and q3 (x, y, z) parameters of the corresponding unit quaternions.
