Roger,

I haven't tried to write files from Matlab using NetCDF Java, but here
is an example of a Matlab using some of the higher level functionality
within NetCDF-Java to access and plot an isosurface from a 3D
dimensionless vertical coordinate ocean model:

http://stellwagen.er.usgs.gov/rps/share/java_isosurface_demo2.m

If you follow the instructions carefully at the top of the m-file to
download the .jar file and edit the classpath, it should just work for
you, as it accesses the model data via OpenDAP, which is supported by
NetCDF-Java.

Let me know if it doesn't work.

Hello,

I hope I'm on the good users list.
I'm working  with Matlab R2006b on Windows. I 'm intesresting by the
NetCDF Java package to access to data files for read and write.
I've found some examples, I try on Matlab, in the document : NetCDF Java
Users' Manuel (page 33-34).

I need some help to call some classes of the librairy nc2.2.jar,
particulary for writing files :
all the classes type ArrayInt (Double, ...) for dimensions D1, D2, D3 ...

I success to manage dimension, attribut, but I don't manage to create a
array of data for any dimension I know.
In Matlab, the instruction :
ucar.ma2.ArrayInt.D3(2, latDim.getLength(), lonDim.getLength()) answers
that the method D3 doesn't exist.
I can't call with the "$" character as it is declared in the package
ucar.ma2.
(ex : ArrayInt$D1).

Is there anybody who have encounter this king of problem ? If yes, could
he/she bring me some help ?
In extension, if anybody has some informations for writing NetCDF files
with Java librairies in Matlab, I'm interesting.

Thanks by advance.
