Every time I see "use ranges and algorithms!" examples, I am baffled that apparently, I am supposed to find
inline double algorithm_call(std::span<double const> xs) noexcept {
return std::accumulate(
xs.begin(),
xs.end(),
0.0,
[](double acc, double volts) {
auto mv = calibrated_mv(volts);
auto err = residual(mv);
return weighted_square(err) + acc;
});
}
more readable, concise, and easier on my eyes than
inline double raw_loop(std::span<double const> xs) noexcept {
double sum = 0.0;
for (double volts : xs) {
auto mv = calibrated_mv(volts);
auto err = residual(mv);
sum += weighted_square(err);
}
return sum;
}
Sure, there are
some algorithms in <algorithms> that I'm rather not reimplement myself, but this one is not it.
