Details:

Is assert([]) valid?
Matlab doesn't allow it with an error about expecting an scalar logical.

I noticed this when looking at some of the uimenu tests where the result of
ishghandle() is used.

It maybe that the real issue here is the test:


hf = figure
uif = findall (hf, "label", "&file1"); % returns empty as no match
assert(ishghandle(uif)) % doesn't complain as ishghandle will correctly return
empty array
