Description

Assigns the value generated by the functor g to the first n elements starting at first (overloads 1,2) or the first n elements in view (overloads 3,4).

Parameters and Requirements

• exespace, first, view, g: same as generate

• label:

  • for 1, the default string is: “Kokkos::generate_n_iterator_api_default”

  • for 3, the default string is: “Kokkos::generate_n_view_api_default”

• n:

  • number of elements to modify (must be non-negative)

Return

If n>0, returns an iterator to the element after the last element modified.

Otherwise, returns first (for 1,2) or Kokkos::begin(view) (for 3,4).
