oa2r

Convert orientation and approach vectors to rotation matrix

R = oa2r(o, a) is an SO(3) rotation matrix (3x3) for the specified orientation and approach vectors (3x1) formed from 3 vectors such that R = [N o a] and N = o x a.

Notes

• The submatrix is guaranteed to be orthonormal so long as O and A are not parallel.
• The vectors O and A are parallel to the Y- and Z-axes of the coordinate frame.
