    const;

Returns a reference to the sub-array obtained by subscripting the first dimension.

Equivalent to SubArray(*this, {index}).

For efficiency, the returned sub-array does not share ownership of the data and stores a view, rather than a copy, of the layout. To share ownership of the data, use the SharedSubArray free function instead.

Dchecks:

rank() > 0

Dchecks:

Contains(domain()[0], index)

Parameters:
Index index

The index into the first dimension.
