Can I Implement a Point-wise Operation via convolution3dLayer?

Hi there,

Because there is no point-wise convolution layer in MATLAB, is that correct if I implement it by

% Suppose that there are n channels in the input, that is, n 2D arrays in the input
filterSize = [1, 1, n];
numFilters = 1;
Padding = 'same';
layer = convolution3dLayer(filterSize, numFilters, PaddingMode, 'same');

That is, I conduct 1 convolution along the thrid dimension of the input only.

An associated question, when I run

layer = convolution3dLayer(filterSize, numFilters, 'PaddingSize', [0, 0, 0; 0, 0, 0])

as per the doc

MATLAB tells me the following:

Error using convolution3dLayer>iParseInputArguments

(line 153)

'PaddingSize' is not a recognized parameter. For a

list of valid name-value pair arguments, see the

documentation for this function.

Error in convolution3dLayer (line 124)

args = iParseInputArguments(varargin{:});

Instead, I have to run

layer = convolution3dLayer(filterSize, numFilters, 'Padding', [0, 0, 0; 0, 0, 0])

I am wondering if that is because the doc has not been updated in time...

Thanks.
