SYNTAX

result = minloc(array, dim [, mask]) result = minloc(array [, mask])

DESCRIPTION

Determines the location of the element in the array with the minimum value, or, if the DIM argument is supplied, determines the locations of the minimum element along each row of the array in the DIM direction. If MASK is present, only the elements for which MASK is .true. 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 MASK are .false., then the result is an array of zeroes. Similarly, if DIM is supplied and all of the elements of MASK along a given row are zero, the result value for that row is zero.

ARGUMENTS

ARRAY	- Shall be an array of type INTEGER, REAL, or CHARACTER.
DIM	- (Optional) Shall be a scalar of type INTEGER, with a value between one and the rank of ARRAY, inclusive. It may not be an optional dummy argument.
MASK	- Shall be an array of type LOGICAL, and conformable with ARRAY.

RETURN VALUE

If DIM is absent, the result is a rank-one array with a length equal to the rank of ARRAY. If DIM is present, the result is an array with a rank one less than the rank of ARRAY, and a size corresponding to the size of ARRAY with the DIM dimension removed. If DIM is present and ARRAY has a rank of one, the result is a scalar. In all cases, the result is of default INTEGER type.

EXAMPLE

sample program:

    program demo_minloc
    integer,save :: ints(3,5)= reshape([&
       1,  2,  3,  4,  5, &
      10, 20, 30, 40, 50, &
      11, 22, 33, 44, 55  &
    ],shape(ints),order=[2,1])
    write(*,*) minloc(ints)
    write(*,*) minloc(ints,dim=1)
    write(*,*) minloc(ints,dim=2)
    end program demo_minloc
