Generate and return .true.
if and only if all elements of the input sequence values are unique.
The uniqueness of the values can be optionally determined by the user by specifying the external input function that checks the equivalence of a pair of elements of the input array
.
[in] | array | : The input contiguous array of shape (:) of either
|
iseq | : The external user-specified function that takes two input scalar arguments of the same type and kind as the input array .It returns a scalar logical of default kind LK that is .true. if the two input arguments are equivalent (e.g., equal) according to the user-defined criterion, otherwise, it is .false. .The following illustrates the generic interface of iseq , function iseq(element1, element2) result(equivalent)
TYPE(KIND) , intent(in) :: element1, element2
logical(LK) :: equivalent
end function

Definition: pm_kind.F90:539 SK , IK , LK , CK , RK , can refer to any kind type parameter that is supported by the processor.This user-defined equivalence check is extremely useful where a user-defined equivalence test other than exact equality or identity is needed, for example, when the array elements should match only within a given threshold or, when the case-sensitivity in character comparisons do not matter. In such cases, the user can define a custom equivalence criterion within the user-defined external function iseq to achieve the goal.(optional, the default equivalence operator is .eqv. if the input array is logical , otherwise == .) |

of default kind LK that is .true.
