inplace : (optional) true or false, with default false

The Reverse command reverses the elements of a Matrix, Vector, or Array into a new Matrix, Vector, or Array of the same shape.

When the option dims is given, it specifies the dimension or dimensions to be reversed.

When inplace=true, the reversal of elements is performed in-place.

$\mathrm{with}\left(\mathrm{ArrayTools}\right)\:$

$A≔\mathrm{Array}\left(\left[1\,2\,3\,4\right]\right)$

$A≔\left[\begin{array}{cccc}1& 2& 3& 4\end{array}\right]$

$\mathrm{Reverse}\left(A\right)$

$\left[\begin{array}{cccc}4& 3& 2& 1\end{array}\right]$

$B≔\mathrm{Vector}\left(\left[''a''\,''b''\,''c''\,''d''\,''e''\right]\right)$

$B≔\left[\begin{array}{c}''a''\\ ''b''\\ ''c''\\ ''d''\\ ''e''\end{array}\right]$

$\mathrm{Reverse}\left(B\,'\mathrm{inplace}'\right)\:$

$B$

$\left[\begin{array}{c}''e''\\ ''d''\\ ''c''\\ ''b''\\ ''a''\end{array}\right]$
