Description:  Returns the location of the maximum value of all elements in an array, a set of elements in an array, or elements in a specified dimension of an array.  
Class:  Transformational function; Generic  
Arguments:  ARRAY  Must be an array of type integer or real.  
DIM (opt)  Must be a scalar integer with a value in the range 1 to n, where n is the rank of ARRAY. This argument is a Fortran 95 feature.  
MASK (opt)  Must be a logical array that is conformable with ARRAY.  
KIND (opt)  Must be a scalar integer initialization expression.  
Results:  The result
is an array of type integer. If KIND is present, the
kind parameter of the result is that specified by KIND; otherwise, the kind
parameter of the result is that of default integer. If the processor
cannot represent the result value in the kind of the result, the result
is undefined.
The following rules apply if DIM is omitted:

Examples
The value of MAXLOC ((/3, 7, 4, 7/)) is (2), which is the subscript of the location of the first occurrence of the maximum value in the rankone array.
A is the array
[ 4 0 3 2 ]
[ 3 1 2 6 ]
[ 1 4 5 5 ].
MAXLOC (A, MASK=A .LT. 5) has the value (1, 1) because these are the subscripts of the location of the maximum value (4) that is less than 5.
MAXLOC (A, DIM=1) has the value (1, 2, 3, 2). 1 is the subscript of the location of the maximum value (4) in column 1; 2 is the subscript of the location of the maximum value (1) in column 2; and so forth.
MAXLOC (A, DIM=2) has the value (1, 4, 3). 1 is the subscript of the location of the maximum value in row 1; 4 is the subscript of the location of the maximum value in row 2; and so forth.
