ALL — All values in MASK along DIM are true#

ALL(MASK, DIM)#

ALL(MASK [, DIM]) determines if all the values are true in MASK in the array along dimension DIM.

Parameters:

  • 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.

Returns:

ALL(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 ALL(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.

Standard:

Fortran 90 and later

Class:

Transformational function

Syntax:
RESULT = ALL(MASK [, DIM])
Example:
program test_all
  logical l
  l = all((/.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 *, all(a .eq. b, 1)
      print *, all(a .eq. b, 2)
    end subroutine section
end program test_all
