<div>If the largest element occurs more than once, then the first occurrence is used.  If <tt>x</tt> has length 0 an error results.<table class="examples"><tr><td><pre>i1 : maxPosition {1,6,4,2}

Notice that the position of the maximal element is 1, as indexing in Macaulay2 always starts at 0.<p>For elements in a polynomial ring, the order used is the <a href="_monomial_sporderings.html">monomial order</a> associated with the ring.</p>
