Description

Check code, and adjust doc so that submat does not allow repeated row/col indexes.

JAA thinks we should exclude repeated row/col indexes because it could easily lead to (nastily) surprising behaviour, and he cannot think of a genuine use for such a feature [well... it could replace FilledMat, I suppose]

submat([0,0,0],[0,0,0], Mat(val);

The code already checks that the indices are distinct -- no idea when this was impl'd (must have been ages ago).

Closing.

NOTE I've just revised the code that checks for repeated indices (now linear instead of quadratic; doubt it makes a difference in practice)
