copied!<p>Based on "Kind of like Map, except with a variable number of arguments." I think you might be looking for <code>Apply</code> to level 1. This is done with:</p> <pre><code>Apply[function, array, {1}] </code></pre> <p>or the shorthand:</p> <pre><code>function @@@ array </code></pre> <p>Here is what it does:</p> <pre><code>array = {{1, 2, 3}, {a, b, c}, {Pi, Sin, Tan}}; action @@@ array </code></pre> <pre><b> {action[1, 2, 3], action[a, b, c], action[Pi, Sin, Tan]} </b></pre> <hr> <p>The terminology I used above could be misleading, and limits the power of <code>Apply</code>. The expression to which you apply <code>action</code> does not need to be a rectangular array. It does not even need to be a <code>List</code>: <code>{...}</code> or have its elements be lists. Here is an example incorporating these possibilities:</p> <pre><code>args = {1, 2} | f[a, b, c] | {Pi}; action @@@ args </code></pre> <pre><b> action[1, 2] | action[a, b, c] | action[Pi] </b></pre> <ul> <li><code>args</code> is not a <code>List</code> but a set of <code>Alternatives</code></li> <li>the number of arguments passed to <code>action</code> varies</li> <li>one of the elements of <code>args</code> has head <code>f</code></li> </ul> <p>Observe that:</p> <ul> <li><code>action</code> replaces the head of each element of <code>args</code>, whatever it may be.</li> <li>The head of <code>args</code> is preserved in the output, in this case <code>Alternatives</code> (short form: <code>a | b | c</code>)</li> </ul>
