NAME
ANY - Determines whether any values are true
SYNOPSIS
ANY ([MASK=]mask [,[DIM=]dim])
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
STANDARDS
Fortran 90
DESCRIPTION
The ANY intrinsic function determines whether any value is true in
argument mask along dimension dim. It accepts the following
arguments:
mask Must be of type logical. It must not be a scalar.
dim Must be a scalar. It must be an integer value in the range
1 <= dim <= n, where n is the rank of mask. The
corresponding actual argument must not be an optional dummy
argument.
ANY is a transformational function. The name of this intrinsic cannot
be passed as an argument.
RETURN VALUES
The result is type logical. It is a scalar result if dim is absent or
if mask has rank one. Otherwise, the result is an array of rank n-1
and of shape (d , d , ..., d , d , ..., d ),
1 2 dim-1 dim+1 n
where (d , d , ..., d )
1 2 n
is the shape of mask.
The result of ANY(mask) has the value TRUE if any element of mask is
true. The result has the value FALSE if no elements of mask are true
or if mask is a zero-sized array.
If mask has rank one, ANY(mask,dim) has a value equal to that of
ANY(mask). Otherwise, the value of
element (s , s , ..., s , s , ..., s )
1 2 dim-1 dim+1 n
of ANY(mask,dim) is equal to
ANY(mask (s , s , ..., s , : , s , ..., s )).
1 2 dim-1 dim+1 n
EXAMPLES
Example 1:
* ANY ( (/ .TRUE., .FALSE., .TRUE. /) ) is .TRUE..
* ANY (mask) is .FALSE. when mask is a zero-sized array.
Example 2: Assume that B and C are arrays as follows:
B is the following array:
| 1 3 5 |
| 2 4 6 |
C is the following array:
| 0 3 5 |
| 7 4 8 |
* ANY ( B .NE. C ) is .TRUE..
* ANY ( B .NE. C, DIM=1 ) is [.TRUE., .FALSE., .TRUE.]
* ANY ( B .NE. C, DIM=2 ) is [.TRUE., .TRUE.].
* ANY ( C .EQ. 1 ) is [.FALSE.] because no elements of the mask are
true.
Example 3: Assume that array N is as follows:
| 0 1 2 3 |
| 4 5 6 7 |
| 8 9 0 1 |
In an array section reference, you can expect the following results:
* ANY((N(2:3,2:4).NE.0)) is .TRUE.
* ANY((N(2:3,2:4).NE.0),DIM=1) is [.TRUE., .TRUE., .TRUE.]
* ANY((N(2:3,2:4).NE.0),DIM=2) is [.TRUE., .TRUE.]
