conv2

---

2-D convolution.

---

Syntax

---

C = conv2(A, B)

C = conv2(u, v, A)

C = conv2(A, B, shape)

C = conv2(u, v, A, shape)

Input argument

---

A

vector or matrix.

B

vector or matrix.

u

row or column vector.

v

row or column vector.

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

2-D convolution, returned as a vector or matrix.

Description

---

conv2 returns the two-dimensional convolution.

Example

---

A = magic(3);
B = magic(4);
R = conv2(A, B, 'same')
