Projection

Projection[u, v]
finds the projection of the vector u onto the vector v.
Projection[u, v, f]
finds projections with respect to the inner product function f.
  • For ordinary vectors u and v, the projection is taken to be . »
  • 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. »
