 <h1 id="prefixes-and-suffixes">Prefixes and Suffixes</h1>
 <p>The Prefixes (<code><span class='Function'>↑</span></code>) function gives a list of all prefixes of its argument array along the <a href="leading.html">first axis</a>, and Suffixes (<code><span class='Function'>↓</span></code>) gives a similar list for suffixes. Because the result can be much larger than the argument, these functions may not be used often in high-performance code, but they are a powerful conceptual tool and can make sense for algorithms that are inherently quadratic.</p>

 <p>The functions are closely related to Take and Drop, as we might expect from their glyphs. Element <code><span class='Value'>i</span><span class='Function'>⊑↑</span><span class='Value'>𝕩</span></code> is <code><span class='Value'>i</span><span class='Function'>↑</span><span class='Value'>𝕩</span></code>, and <code><span class='Value'>i</span><span class='Function'>⊑↓</span><span class='Value'>𝕩</span></code> is <code><span class='Value'>i</span><span class='Function'>↓</span><span class='Value'>𝕩</span></code>.</p>
 <p>In both cases, an empty array and the entire argument are included in the result, meaning its length is one more than that of the argument. Using <a href="logic.html">Span</a>, we can say that the result has elements whose lengths go from <code><span class='Number'>0</span></code> to <code><span class='Function'>≠</span><span class='Value'>𝕩</span></code>, inclusive, so there are <code><span class='Paren'>(</span><span class='Function'>≠</span><span class='Value'>𝕩</span><span class='Paren'>)</span><span class='Function'>¬</span><span class='Number'>0</span></code> or <code><span class='Number'>1</span><span class='Function'>+≠</span><span class='Value'>𝕩</span></code> elements. The total number or cells in the result (for example, <code><span class='Function'>≠∾↑</span><span class='Value'>𝕩</span></code> or <code><span class='Function'>+</span><span class='Modifier'>´</span><span class='Function'>≠</span><span class='Modifier'>¨</span><span class='Function'>↑</span><span class='Value'>𝕩</span></code>) scales with the square of the argument length—it is quadratic in <code><span class='Function'>≠</span><span class='Value'>𝕩</span></code>. We can find the exact total by looking at Prefixes and Suffixes together:</p>

 <p>We might view a slice as a selection for not two but <em>three</em> parameters: the number of cells before, in, and after the slice. The conditions are that each parameter, being a length, is at least 0, and the total of the three parameters is equal to the array length. With three parameters and one equality constraint, the space of slices is two-dimensional; the above ways to enumerate it each pick two parameters and allow the third to be dependent on these two. If you're familiar with <a href="https://en.wikipedia.org/wiki/Barycentric_coordinate_system">barycentric coordinates</a> on a triangle, this should sound very familiar because that's exactly what the three parameters are!</p>
 <p>We might also consider the question of slices along multiple axes. Because axes are orthogonal, we can choose such a slice by independently slicing along each axis. To use the homogeneous shape of arrays as much as possible, the result should still only have two added layers of nesting for the two coordinates we choose, with all possible choices for the first axis along the axes of the outer array and those for the second along the axes of each inner array. Our Windows-based solution adapts to multidimensional arrays easily:</p>
