Slicing in Masked Arrays (MA)

Question

Are indexing and slicing treated differently in MA vs. Numeric?

Answer

Yes, they are, in that slices (that return non-scalar results) in MA return actual copies of the data while slices in Numeric return references. For a detailed description see the numarray manual's description of the difference. (The same answer applies to the version of MA bundled with Numeric.)
