For vector V, the function sort(V) will return a vector W with the same dimensions as V.  The elements of W are the elements of V sorted in numerical and lexicographical order.

For polynomial p, the function sort(p) will return a polynomial q which is equal to p, but with the terms ordered by descending degree.

$v≔\mathrm{Array}\left(\left[g\,24\,3\,e\,\mathrm{`12a`}\right]\right)$

$v≔\left[\begin{array}{ccccc}g& 24& 3& e& \mathrm{12a}\end{array}\right]$

$\mathrm{sort}\left(v\right)$

$\left[\begin{array}{ccccc}3& 24& \mathrm{12a}& e& g\end{array}\right]$

$u≔\mathrm{sort}\left(4x+x^4-x^2\right)$

$u≔x^4-x^2+4x$
