conv

Convolution and polynomial multiplication.

Syntax

• C = conv(u, v)
• C = conv(u, v, shape)

Input argument

• u - input vectors, specified as either row or column vectors.
• v - input vectors, specified as either row or column vectors.
• shape - subsection of convolution: 'full' (default: full 2-D convolution), 'same' (central part of the convolution) or 'valid' (parts of the convolution that are computed without zero-padded edges).

Output argument

• C - convolution, returned as a vector or matrix.

Description

conv returns the convolution of vectors u and v.

Example

U = [-1 2 3 -2 0 1 2];
V = [2 4 -1 1];
R = conv(U, V, 'same')
