Question

How is convolution used in polynomial multiplication?

Answer 1

ANSWER:-

The convolution of two vectors, u and v , represents the area of overlap under the points as v slides across u .

Algebraically, convolution is the same operation as multiplying polynomials whose coefficients are the elements of u and v .

w ( k ) = ∑ j u ( j ) v ( k − j + 1 ) .
