WebNumPy arrays support this interface, as do Cython arrays. The “nearly all” is because the Python buffer interface allows the elements in the data array to themselves be pointers; Cython memoryviews do not yet support this. Memory layout ¶ The buffer interface allows objects to identify the underlying memory in a variety of ways. WebAug 6, 2008 · 1. A pure python implementation: Easy to read and modify --- it can be cut out into a python source code. 2. A straight forward cython implementation: About 4 times as fast as the python implementation. 3. An optimised cython implementation earning another factor of 2 in speed (depends on the parameters used).
