Transformational Intrinsic Function (Generic): Reduces an array with a bitwise AND operation.
result = IALL (array, dim [, mask])
result = IALL (array[, mask])
array |
(Input) Must be an array of type integer. |
dim |
(Input) Must be a scalar integer with a value in the range 1 <= dim <= n, where n is the rank of array. The corresponding actual argument must not be an optional dummy argument. |
mask |
(Input; optional) Must be of type logical and conformable with array. |
The result has the same type and kind parameters as array. It is scalar if dim does not appear or if array has rank one; otherwise, the result is an array of rank n - 1 and shape [d1, d2, ..., ddim-1, ddim+1 , ..., dn] where [d1, d2,..., dn] is the shape of array.
If array has size zero the result value is equal to NOT (INT (0, KIND (array))). Otherwise, the result of IALL (array) has a value equal to the bitwise AND of all the elements of array.
The result of IALL (array, MASK=mask) has a value equal to IALL (PACK (array, mask)).
The result of IALL (array, DIM=dim [ , MASK=mask]) has a value equal to that of IALL (array [ , MASK=mask]) if array has rank one. Otherwise, the value of element (s1, s2, ..., sdim-1, sdim+1 , ..., sn) of the result is equal to IALL (array (s1, s2, ..., sdim-1 , :, sdim+1 , ..., sn) [, MASK = mask (s1, s2, ..., sdim-1 , :, sdim+1 , ..., sn)]).
IALL ([14, 13, 11]) has the value 8. IALL ([14, 13, 11], MASK=[.true., .false., .true]) has the value 10.
