 the index of the first element, and @var{nelems} is the number of

+You may use @sampl{@@} twice to generate a two-dimensional slice
+from a one-dimensional array.  This permits viewing a one-dimensional
+array as a table (see @pxref{Arrays as Tables}) and looks as follows:
+
address@hidden
+graph display @address@hidden@@@var{nelems1}@@@var{nelems2}
address@hidden example

 The left operand of @samp{@@} must reside in memory.  Array values made
 with @samp{@@} in this way behave just like other arrays in terms of
 subscripting, and are coerced to pointers when used in expressions.
