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

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

matrix.flat A 1-D iterator over the array. This is a

matrix.swapaxes(axis1, axis2) Return a view of the array with axis1 and axis2 interchanged.

recarray.dtype Data-type of the array?s elements.

matrix.any(axis=None, out=None)

matrix.setflags(write=None, align=None, uic=None) Set array flags WRITEABLE, ALIGNED, and UPDATEIFCOPY, respectively.

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

matrix.H Returns the (complex) conjugate transpose of self. Equivalent to np.transpose(self)

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