Example

std::array<int, 10> input

{

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

};

std::array<int, 10> output;

etl::threshold<int> threshold(4, 0, 9); // Compares each value to 4 and output 0 or 9.

std::transform(input.begin(), input.end(), output.begin(), threshold);

// output == 0, 0, 0, 0, 9, 9, 9, 9, 9, 9
