FirstLocScalar¶
The FirstLocScalar is a class template that stores a location (index) of the first occurrence satisfying a condition as a single, convenient unit.
It’s designed to hold the result of parallel_reduce() operations using a FirstLoc builtin reducer.
It is generally recommended to get this type by using the reducer’s
::value_type member (e.g., FirstLoc<Index,Space>::value_type)
to ensure the correct template parameters are used.

Usage¶
FirstLocScalar<Index>::value_type result;
parallel_reduce(N,Functor,FirstLocScalar<Index>(result));
I firstLoc = result.min_loc_true;
