...e, a unit DType could use this to wrap an existing floating point DType without needing to re-implement low-level ufunc logic. In the unit example, resolve_descriptors would handle computing the output unit from the input unit. typedef...

...dex is called. This function also resets the iterator to its initial state. WARNING: This function changes the internal logic of the iterator. Any cached functions or pointers from the iterator must be retrieved again! Returns NPY_SUCCEED o...
Indexing on ndarrays
...d indexing operations are inserted into the result array at the same spot as they were in the initial array (the latter logic is what makes simple advanced indexing behave just like slicing). Example Suppose x.shape is (10, 20, 30) and ind...
Iterating over arrays
...loop In all the examples so far, the elements of a are provided by the iterator one at a time, because all the looping logic is internal to the iterator. While this is simple and convenient, it is not very efficient. A better approach is t...

NumPy 1.18.0 Release Notes
...r arrays as fill values in ma.fill_value Setting a MaskedArray.fill_value to a non-scalar array is deprecated since the logic to broadcast the fill value to the array is fragile, especially when slicing. (gh-13698) Deprecate PyArray_As1D,...
