Web2.8.5.2. Numpy Support¶ Cython has support for Numpy via the numpy.pyx file which allows you to add the Numpy array type to your Cython code. I.e. like specifying that variable i is of type int, you can specify that variable a is of type numpy.ndarray with a given dtype. Also, certain optimizations such as bounds checking are supported.
