what is u hat over here?
I mean what will be the elements of the u hat if i take u as (1,0,0)

[@anandnarawade8183]

If u = [u1 u2 u3] then
u hat =[[0 -u3 u2]
[u3 0 -u1]
[-u2 u1 0]]

[@rui255]

uhat is the skew symmetric matrix [[0 -u3 u2], [u3 0 -u1], [-u2 u1 0]]

@@rui255 also normalized to unit length I think
