<dd><p>Determines the minimum value of the elements in an array value, or, if
|
|
the <var>DIM</var> argument is supplied, determines the minimum 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 <code>CHAR(255)</code> characters if
|
|
<var>ARRAY</var> is of character type.
