Array API
...ray_STRIDE(PyArrayObject *arr, int n) Return the stride in the n \(^{\textrm{th}}\) dimension. npy_intp PyArray_ITEMSIZE(PyArrayObject *arr) Return the itemsize for the elements of this array. Note that, in the old API that was deprecat...

...t is usually cast to PyArrayIterObject* so that its members can be accessed. The only members that are needed are iter->size which contains the total size of the array, iter->index, which contains the current 1-d index into the array, and i...

Iterating over arrays

Linear algebra (numpy.linalg)

NumPy 1.10.0 Release Notes
...dimensions are now required to be present in input arrays; core dimensions with the same label must have the exact same size; and output core dimension’s must be specified, either by a same label input core dimension or by a passed-in outpu...

...of complex types is now the same as a C-struct composed of two floating point values, while before it was equal to the size of the type. For many users (for instance on x64/unix/gcc) this means that complex64 is now 4-byte aligned instead...

NumPy 1.23.0 Release Notes
...mensional indexing with anything but a tuple was deprecated in NumPy 1.15. (gh-21029) Changing to a dtype of different size in F-contiguous arrays is no longer permitted. Deprecated since Numpy 1.11.0. See below for an extended explanation...
