Given a set of nodes , which must all be distinct, for indices , the Lagrange basis for polynomials of degree for those nodes is the set of polynomials each of degree which take values if and . Using the Kronecker delta this can be written Each basis polynomial can be explicitly described by the product: Notice that the numerator has roots at the nodes while the denominator scales the resulting polyn… WebCurve fitting#.
