Function Reference
— Function File: c = convn (a, b, shape)

N-dimensional convolution of matrices a and b.

The size of the output is determined by the shape argument. This can be any of the following character strings:

"full"
The full convolution result is returned. The size out of the output is size (a) + size (b)-1. This is the default behaviour.
"same"
The central part of the convolution result is returned. The size out of the output is the same as a.
"valid"
The valid part of the convolution is returned. The size of the result is max (size (a) - size (b)+1, 0).
