struct MatShape#
Represents shape of a matrix/tensor. Previously, MatShape was defined as an alias of std::vector<int>, but now we use a special structure that provides a few extra benefits:
avoids any heap operations, since the shape is stored in a plain array. This reduces overhead of shape inference etc.
includes information about the layout, including the actual number of channels (‘C’) in the case of block layout.
distinguishes between empty shape (total() == 0) and 0-dimensional shape (dims == 0, but total() == 1).
