问题 I'm working on a project where I have a number of arrays of the same size in the 1st, 2nd and 3rd dimension, although the sizes may vary in the 4th dimension. I would like to group these arrays by constructing a pointer which concatenates these arrays. To make this less abstract, let's say I have 2 arrays: A (size: N1 x N2 x N3 x N4a) B (size: N1 x N2 x N3 x N4b) in previous versions of the project these arrays where copied to an array C of size N1 x N2 x N3 x (N4a + N4b) which would then be
