Hello,
perfect, this looks like what I was looking for. Exactly, I am aware of the interpretation of the conv as an application of a matrix to a vector. I knew that for 2D, one typically only has to rotate the filter to obtain the tranposed operation. But since for 3D there are multiple possibilities to rotate the filter, I was wondering if there was a function which does this without me having to take care of how exactly to manipulate the filter depending on the dimensionality of the problem.
Thanks a lot again!
