IALL — Bitwise AND of array elements
Reduces with bitwise AND the elements of ARRAY along dimension DIM if the corresponding element in MASK is
Fortran 2008 and later
RESULT = IALL(ARRAY[, MASK])
RESULT = IALL(ARRAY, DIM[, MASK])
ARRAY Shall be an array of type
DIM (Optional) shall be a scalar of type
INTEGERwith a value in the range from 1 to n, where n equals the rank of ARRAY.
MASK (Optional) shall be of type
LOGICALand either be a scalar or an array of the same shape as ARRAY.
- Return value:
The result is of the same type as ARRAY.
If DIM is absent, a scalar with the bitwise ALL of all elements in ARRAY is returned. Otherwise, an array of rank n-1, where n equals the rank of ARRAY, and a shape similar to that of ARRAY with dimension DIM dropped is returned.
