bilby.gw.geometry.rotation_matrix_from_delta

bilby.gw.geometry.rotation_matrix_from_delta(delta_x)

Calculate rotation matrix from a delta vector.

Parameters:

delta_x: array-like

3D vector \(\vec{\Delta}x\) representing the separation or orientation.

Returns:

array-like

3x3 rotation matrix that rotates the z-axis to align with \(\vec{\Delta}x\) direction.
