- NumPy 2.0.0 Release Notes
...rs support for calculating the matrix transpose of an array (or stack of arrays). The matrix transpose is equivalent to swapping the last two axes of an array. Both np.ndarray and np.ma.MaskedArray now expose a .mT attribute, and there is a...

...('c', '<f4')]) This obeys the structured array assignment rules described above. For example, this means that one can swap the values of two fields using appropriate multi-field indexes: >>> a[['a', 'c']] = a[['c', 'a']] Indexing with...

...writeable, aligned, and in machine byte-order using PyArray_FromAny. If you wish to handle all types of arrays, the copyswap function for each type is useful for handling misbehaved arrays. Some platforms (e.g. Solaris) do not like misalign...
- How to extend NumPy
...AYMake sure the resulting object is an actual ndarray and not a sub- class. Note Whether or not an array is byte-swapped is determined by the data-type of the array. Native byte-order arrays are always requested by PyArray_FROM_OTF a...
- NumPy 1.21.0 Release Notes
...np.random.Generator.uniform. Raises ValueError if low > high. Previously out-of-order inputs were accepted and silently swapped, so that if low > high, the value generated was high + (low - high) * random(). (gh-17921) /usr/include remove...
