NAME

any(3f) - [FORTRAN:INTRINSIC:ARRAY REDUCTION] determines if any of the values in the logical array are true.

SYNTAX

result = any(mask [, dim])

DESCRIPTION

ANY(MASK [, DIM]) determines if any of the values in the logical array MASK along dimension DIM are .TRUE..

ARGUMENTS

MASK	the type of the argument shall be LOGICAL and it shall not be scalar.
DIM	(optional) DIM shall be a scalar integer with a value that lies between one and the rank of MASK.

RETURN VALUE

ANY(MASK) returns a scalar value of type LOGICAL where the kind type parameter is the same as the kind type parameter of MASK. If DIM is present, then ANY(MASK, DIM) returns an array with the rank of MASK minus 1. The shape is determined from the shape of MASK where the DIM dimension is elided.

1.	ANY(MASK) is true if any element of MASK is true; otherwise, it is false. It also is false if MASK has zero size.
2.	If the rank of MASK is one, then ANY(MASK, DIM) is equivalent to ANY(MASK). If the rank is greater than one, then ANY(MASK, DIM) is determined by applying ANY to the array sections.

EXAMPLE

Sample program:

    program demo_any
    implicit none
    logical l
       l = any([.true., .true., .true.])
       print *, l
       call section
       contains
         subroutine section
         integer a(2,3), b(2,3)
           a = 1
           b = 1
           b(2,2) = 2
           print *, any(a .eq. b, 1)
           print *, any(a .eq. b, 2)
         end subroutine section
    end program demo_any
