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.

DetailsDetails

  • 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. »
