BroadcastIterator#

class numpy::BroadcastIterator#: Iterator class for array traversal.

Example#

#include <numpy/np_ndarray.h>
using namespace numpy;

// Use BroadcastIterator
NDArray<double> arr = np::arange<double>(12).reshape({3, 4});
for (auto it = arr.begin(); it != arr.end(); ++it) {
    // ... process elements ...
}
