But I never say the contrary dpb.
IIRC, the behavior of a:b:c when a, b, c are (pure real) arrays are documented recently, (after the thread I provide the like earlier).
But the behavior for complex ins't (yet?) documenetd. Though the same behavior is reproductible in all MATLAB versions: it operates only on real part first element of the inputs. That's logical and meaningful IMO.
There are many things that are not documented. Just take a look at Yair's blog. Are things discussed there are meaningless to you? I thing Yair's blog is the most useful blog concerning MATLAB.
In many languages - even a strict one like C - the behavior of many function is not completely defined (such as malloc(0), or something as simple as the bit shift (a >> b)). The specific compiler will implement specific behavior, yet all of them are meaningful. Just like MATLAB colon.
