Cauchy product

Summary

The Cauchy product of two series is the series whose nn-th term is the sum of the products akbn−ka_k b_{n-k}. It is the discrete convolution of the two sequences of terms. The node Cauchy product gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
