The 2nd argument is the `strides`. IOW it is just specifying how to traverse the buffer in memory to visit each of the dimensions. For the first example where `strides` is not specified, Python makes them C-ordered. IOW `m2.strides` would be `(3, 1)`. Effectively this is represented like this: ``` [[ b"a", b"c", b"e"], [ b"b", b"d', b"f"]] ``` For the second case where strides are overridden (so `m2.strides` would be `(1, 2)`), we get something like this: ``` [[b"a", b"b", b"c"], [b"d", b"e", b"f"]] ``` In either case the `1` here has specified which dimension is fastest to traverse along. IOW that content is adjacent in memory. Should add the reason it is `1` is that for `uint8_t` (or format "B"), this is that type's size. If we had a different format, this would be the size of that format.
