MaskedArray.diagonal()

numpy.ma.MaskedArray.diagonal

MaskedArray.diagonal(offset=0, axis1=0, axis2=1) [source]

Return specified diagonals. In NumPy 1.9 the returned array is a read-only view instead of a copy as in previous NumPy versions. In a future version the read-only restriction will be removed.
