filter2

---

2-D digital filter.

---

Syntax

---

Y = filter2(H, X)

Y = filter2(H, X, shape)

Input argument

---

H

coefficients of rational transfer function.

X

input data.

shape

'same' (default), 'valid' or 'full'.

Output argument

---

Y

result: 2-D digital filter.

Description

---

Y = filter2(H, X) applies a finite impulse response filter to a matrix of data X according to coefficients in a matrix H.

Example

---

A = zeros(10);
A(3:7, 3:7) = ones(5);
H = [1 2 1; 0 0 0; -1 -2 -1];
R = filter2(H, A, 'valid')
