I think its more complicated than that, but yet it is a known issue that hasn't
been corrected yet. May already be an open issue here.

I've made some changes to geosubset. They work for the dataset above, but will
need to be tested for the various arrangements of time/lat/lon, z/lat/lon,
time/z/lat/lon including the 2-d lat/lon as well as the 1-d lat/lon of
different lengths.

We need to figure out h_stride. Right now h_stride(1) is the rows stride, and
h_stride(2) is columns stride, if the lat/lon coordinates are 2-d matrices. If
the lat/lon coordinates are different length 1-d arrays, then h_stride(1) is
lat stride, and h_stride(2) is lon stride I think...

How about if we use the same syntax that ERDDAP uses?
They put the stride right in the middle of the lon request, like this:
s.lon_range=[-71.5:2:-65.5]
s.lat_range=[38.0:3:46.0]

Oops. I guess the arguments would have to be strings, though, if we did that,
like
s.lon_range='-71.5:2:-65.5'
or else Matlab would not pass the right thing.
Maybe s.lon_range
s.lon_stride
s.lat_range
s.lon_stride
is better

I think that the lon/lat_stride option won't quite work with very curvilinear
datasets. (its technically incorrect for any curvilinear datasets I think). its
really like an i/j horizontal stride, maybe we should just make the only option
to be one number for horizontal striding?

It certainly is an i,j stride, not a lon/lat stride, but stride *should* work
for any structured grid, not matter how curvy it is, because logically the data
is just a 2D (or 3D, or 4D) in [(n),(k),j,i] space.

I just meant the terminology is confusing. Maybe we just have one single number
as a horizontal stride parameter.

So does "fixed" mean that now only 1 number is allowed for horizontal stride?

No, i think 2 is still allowed. I had already fixed the original problem, and
this was hanging around as an unfinished issue.
