    v: &Vector<N, U2, S>
) -> Option<(UnitComplex<N>, N)>

Expand description

Computes the rotation R required such that the y component of R * v is zero.

Returns None if no rotation is needed (i.e. if v.y == 0). Otherwise, this returns the norm of v and the rotation r such that R * v = [ |v|, 0.0 ]^t where |v| is the norm of v.
