python max matrix index
numpy.argmax¶. numpy.argmax(a, axis=None, out=None)[source]¶. Returns the indices of the maximum values along an axis. Parameters: a : array_like. Input array. axis : int, optional. By default, the index is into the flattened array, otherwise along the sp, Numpy has an argmax function that returns just that, although you will have to deal with the nan s manually. nan s always get sorted to the end of an array, so with that in mind you can do: a = np.random.rand(10000) a[np.random.randint(10000, size=(10,))
