matrix.diagonal(offset=0, axis1=0, axis2=1) Return specified diagonals. In NumPy 1.9 the returned array is a read-only

matrix.conj() Complex-conjugate all elements. Refer to numpy.conjugate for full documentation.

matrix.choose(choices, out=None, mode='raise') Use an index array to construct a new array from a set of choices. Refer

matrix.argpartition(kth, axis=-1, kind='introselect', order=None) Returns the indices that would partition this array

recarray.byteswap(inplace) Swap the bytes of the array elements Toggle between low-endian and big-endian data

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

matrix.getA1()

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

matrix.take(indices, axis=None, out=None, mode='raise') Return an array formed from the elements of a at the given

class numpy.recarray
