Re: str2double behavior

[Rik]

One last question before I post a changeset for comments.

Does Matlab return a complex NaN or real NaN for unparseable inputs?

str2double ({ "abc"; "4i" })

returns

   NaN +   0i
     0 +   4i

with the current 3.4.0 implementation.  It seems like it should be NaN +
NaNi instead.  If Matlab returns NaN + NaNi, then are they being extra
clever and narrowing results to real if the only complex values are NaN?

Test case is

str2double ({ "abc"; "4" })


Thanks,
