numpy.ma.masked_array.diagonal

masked_array.diagonal(offset=0, axis1=0, axis2=1)

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 NumPy 1.10 the read-only restriction will be removed.

Refer to numpy.diagonal for full documentation.
