# conv2

2-D convolution

## Description

returns the two-dimensional
convolution of matrices `C`

= conv2(`A`

,`B`

)`A`

and `B`

.

If

`A`

is a matrix and`B`

is a row vector (or`A`

is a row vector and`B`

is a matrix), then`C`

is the convolution of each row of the matrix with the vector.If

`A`

is a matrix and`B`

is a column vector (or`A`

is a column vector and`B`

is a matrix), then`C`

is the convolution of each column of the matrix with the vector.
