Constructor & Destructor Documentation

rottoax()

subroutine pmat4::rottoax::rottoax ( real(dp), dimension(3,3), intent(in)  orth33, real(dp), dimension(3), intent(out)  ax3  )

private

Assuming that given orth33 is a 3*3 proper rotation matrix, derive an axial 3-vector, ax3, such that orth33 is implied by ax3 when the latter is interpreted as encoding a rotation (as in subroutine axtorot).

Note that such ax3 are not unique – adding any multiple of 2*pi times the parallel unit vector leads to the same orth33.

Parameters

[in]	orth33	3*3 proper rotation matrix
[out]	ax3	axial 3-vector
