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

record.choose() Not implemented (virtual attribute) Class generic exists solely to derive numpy scalars from, and

ndarray.cumsum(axis=None, dtype=None, out=None) Return the cumulative sum of the elements along the given axis. Refer

recarray.trace(offset=0, axis1=0, axis2=1, dtype=None, out=None) Return the sum along diagonals of the array. Refer

recarray.nonzero() Return the indices of the elements that are non-zero. Refer to

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

ndarray.__long__() <==> long(x)

ndarray.partition(kth, axis=-1, kind='introselect', order=None) Rearranges the elements in the array in such a way that

ndarray.__contains__ x.__contains__(y) <==> y in x

ndarray.__hex__() <==> hex(x)
