covn函數(shù)：

主要進(jìn)行N維上的卷積，就是【 m n k】三維矩陣上的卷積

N-dimensional convolution

Syntax

• C = convn(A,B) C = convn(A,B,'shape')

Description

C = convn(A,B)?computes the N-dimensional convolution of the arrays?A?and?B. The size of the result is?size(A)+size(B)-1.

C = convn(A,B,'shape')?returns a subsection of the N-dimensional convolution, as specified by the?shape?parameter:

對(duì)邊界處理的三種形式：

'full'	Returns the full N-dimensional convolution (default).
'same'	Returns the central part of the result that is the same size as?A.
'valid'	Returns only those parts of the convolution that can be computed without assuming that the array?A?is zero-padded. The size of the result is? max(size(A)-size(B) + 1, 0)
