finds the projection of the vector u onto the vector v.
finds projections with respect to the inner product function f.
- For ordinary real vectors u and v, the projection is taken to be .
- For ordinary complex vectors u and v, the projection is taken to be , where is Conjugate[v].
- In Projection[u,v,f], u and v can be any expressions or lists of expressions for which the inner product function f applied to pairs yields real results. »
