<h1>MMULT Function</h1>
<p>The <b>MMULT</b> function is one of the math and trigonometry functions. It is used to return the matrix product of two arrays and display the first value of the returned array of numbers.</p>
<p>The <b>MMULT</b> function syntax is:</p>
<p style="text-indent: 150px;"><b><em>MMULT(array1, array2)</em></b></p>
<p>where <b><em>array1, array2</em></b> is an array of numbers.</p>
<p class="note"><b>Note</b>: if any of the cells in the array contain empty or non-numeric values, the function will return the <b>#N/A</b> error.<br />
If the number of columns in <b><em>array1</em></b> is not the same as the number of rows in <b><em>array2</em></b>, the function will return the <b>#VALUE!</b> error.</p>
<p>To apply the <b>MMULT</b> function,</p>
<ol>
<li>select the cell where you wish to display the result,</li>
