/**
 * Implementation for the Excel function SUMPRODUCT<p>
 *
 * Syntax : <br>
 *  SUMPRODUCT ( array1[, array2[, array3[, ...]]])
 *    <table>
 *      <caption>Parameter descriptions</caption>
 *      <tr><th>array1, ... arrayN&nbsp;&nbsp;</th><td>typically area references,
 *      possibly cell references or scalar values</td></tr>
 *    </table><br>
 *
 * Let A<b>n</b><sub>(<b>i</b>,<b>j</b>)</sub> represent the element in the <b>i</b>th row <b>j</b>th column
 * of the <b>n</b>th array<br>
 * Assuming each array has the same dimensions (W, H), the result is defined as:<br>
 * SUMPRODUCT = &Sigma;<sub><b>i</b>: 1..H</sub> &nbsp;
 *  (&nbsp; &Sigma;<sub><b>j</b>: 1..W</sub> &nbsp;
 *    (&nbsp; &Pi;<sub><b>n</b>: 1..N</sub>
 *          A<b>n</b><sub>(<b>i</b>,<b>j</b>)</sub>&nbsp;
 *    )&nbsp;
 *  )
 *
 * <p>
 *     The current implementation does not support the more advanced use cases of SUMPRODUCT, including
 *     <code>SUMPRODUCT((B2:B9=B12)*(C2:C9=C12)*D2:D9)</code> (see example 3 in
 *     https://support.microsoft.com/en-us/office/sumproduct-function-16753e75-9f68-4874-94ac-4d2145a2fd2e).
