Details:

I have received the following email from Brendon Higgins (added to CC) with a
bug report to degrees2dm and patch (attached):

> I  have found that the OctaveForge function degrees2dm(deg) fails when any
> value in the input vector deg is NaN:
> >> degrees2dm([NaN 3 6757 23421 NaN 1.2345])
> error: invalid conversion from NaN to logical
> error: called from
>     degrees2dm at line 90 column 10
>
> In comparison, Matlab's implementation handles this input gracefully by
> returning [NaN, NaN] for each such value.
>
> For your consideration, I attach a modified version of dergees2dm.m,
wherein
> I've attempted to avoid the call to logical() for dm rows containing NaN.
It
> would be great if a future version contained such a fix.
