| <dl compact="compact"> |
| <dt><em>Description</em>:</dt> |
| <dd><p>Determines the location of the element in the array with the minimum |
| value, or, if the <var>DIM</var> argument is supplied, determines the |
| locations of the minimum element 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 more than one |
| element in the array has the minimum value, the location returned is |
| that of the first such element in array element order. If the array has |
| zero size, or all of the elements of <var>MASK</var> are <code>.FALSE.</code>, then |
| the result is an array of zeroes. Similarly, if <var>DIM</var> is supplied |
| and all of the elements of <var>MASK</var> along a given row are zero, the |
| result value for that row is zero. |

| <dt><em>Arguments</em>:</dt> |
| <dd><table> |
| <tr><td width="15%"><var>ARRAY</var></td><td width="70%">Shall be an array of type <code>INTEGER</code> or |
| <code>REAL</code>.</td></tr> |

| <code>INTEGER</code>, with a value between one and the rank of <var>ARRAY</var>, |
| inclusive. It may not be an optional dummy argument.</td></tr> |
| <tr><td width="15%"><var>MASK</var></td><td width="70%">Shall be an array of type <code>LOGICAL</code>, |
| and conformable with <var>ARRAY</var>.</td></tr> |
| </table> |
| |
| </dd> |
| <dt><em>Return value</em>:</dt> |
| <dd><p>If <var>DIM</var> is absent, the result is a rank-one array with a length |
| equal to the rank of <var>ARRAY</var>. 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. If <var>DIM</var> is present and <var>ARRAY</var> has a rank |
| of one, the result is a scalar. In all cases, the result is of default |
| <code>INTEGER</code> type. |
