ndarray.reshape(shape, order='C') Returns an array containing the same data with a new shape. Refer to

ndarray.size Number of elements in the array. Equivalent to np.prod(a.shape), i.e., the product of

ndarray.prod(axis=None, dtype=None, out=None, keepdims=False) Return the product of the array elements over the given axis

ndarray.round(decimals=0, out=None) Return a with each element rounded to the given number of decimals.

ndarray.argsort(axis=-1, kind='quicksort', order=None) Returns the indices that would sort this array. Refer to

ndarray.item(*args) Copy an element of an array to a standard Python scalar and return it.

ndarray.newbyteorder(new_order='S') Return the array with the same data viewed with a different byte order. Equivalent

ndarray.squeeze(axis=None) Remove single-dimensional entries from the shape of a. Refer to

ndarray.__lshift__ x.__lshift__(y) <==> x<<y

ndarray.__ne__ x.__ne__(y) <==> x!=y
