5.6 Reversing functions
Stan provides functions to create a new array by reversing the order of
elements in an existing array. For example, if v
is declared as a real
array of size 3, with values
\[ \text{v} = (1,\, -10.3,\, 20.987), \] then
\[ \mathrm{reverse(v)} = (20.987,\, -10.3,\, 1). \]
array[] T
reverse
(array[] T v)
Return a new array containing the elements of the argument in reverse order.
