If you start with a contiguous array (roughly speaking, where all values
are stored in a single block of memory), view_as_blocks can provide a
new "view" on the array without making any copies of the underlying
data: it does this by manipulating the array strides. This is not
always possible, so while it will still create the structure you seek,
it makes a copy underneath the hood. We warn users about this, because
it may be slow, and it may impact memory use.
Best regards
