<h3 class="section">8.165 <code>MAXVAL</code> — Maximum value of an array</h3>
<p><a name="index-MAXVAL-835"></a><a name="index-array_002c-maximum-value-836"></a><a name="index-maximum-value-837"></a>
<dl>
<dt><em>Description</em>:<dd>Determines the maximum value of the elements in an array value, or, if
the <var>DIM</var> argument is supplied, determines the maximum value along
each row of the array in the <var>DIM</var> direction. If <var>MASK</var> is
present, only the elements for which <var>MASK</var> is <code>.TRUE.</code> are
considered. If the array has zero size, or all of the elements of
<var>MASK</var> are <code>.FALSE.</code>, then the result is <code>-HUGE(ARRAY)</code>
if <var>ARRAY</var> is numeric, or a string of nulls if <var>ARRAY</var> is of character
type.
<br><dt><em>Standard</em>:<dd>Fortran 95 and later
<br><dt><em>Class</em>:<dd>Transformational function
<br><dt><em>Syntax</em>:<dd>
<p><table summary=""><tr align="left"><td valign="top" width="80%"><code>RESULT = MAXVAL(ARRAY, DIM [, MASK])</code>
<br></td></tr><tr align="left"><td valign="top" width="80%"><code>RESULT = MAXVAL(ARRAY [, MASK])</code>
<br></td></tr></table>
<br><dt><em>Arguments</em>:<dd>
<p><table summary=""><tr align="left"><td valign="top" width="15%"><var>ARRAY</var> </td><td valign="top" width="70%">Shall be an array of type <code>INTEGER</code> or
<code>REAL</code>.
<br></td></tr><tr align="left"><td valign="top" width="15%"><var>DIM</var> </td><td valign="top" width="70%">(Optional) Shall be a scalar of type
<code>INTEGER</code>, with a value between one and the rank of <var>ARRAY</var>,
inclusive. It may not be an optional dummy argument.
<br></td></tr><tr align="left"><td valign="top" width="15%"><var>MASK</var> </td><td valign="top" width="70%">Shall be an array of type <code>LOGICAL</code>,
and conformable with <var>ARRAY</var>.
<br></td></tr></table>
<br><dt><em>Return value</em>:<dd>If <var>DIM</var> is absent, or if <var>ARRAY</var> has a rank of one, the result
is a scalar. If <var>DIM</var> is present, the result is an array with a
rank one less than the rank of <var>ARRAY</var>, and a size corresponding to
the size of <var>ARRAY</var> with the <var>DIM</var> dimension removed. In all
cases, the result is of the same type and kind as <var>ARRAY</var>.
