netcdf reading in stand-alone applications

Dear all!

I read netcdf files with netcdf toolbox as

sl= netcdf('nrt_global_merged_msla.nc','nowrite');

It works ok

But! When I create a stand-alone application with MCR the programm didn't work

It writes

Error in ==> ncmex at 139

Error in ==> netcdf.open at 20

Error in ==> netcdf.netcdf at 416

Error in ==> test_errors_nc at 4

MATLAB:UndefinedFunction

I try to copy netcdf.dll into programm folder, but .exe file didn't work!

Please help me!
Respect!

I have the same problem! Did you find any solution??

Best Regards!

I don't know what MCR means.
But if you can read a .nc file using netcdf, you should be able to
write one like this:
nc=netcdf(ncfile,'clobber');
nc.description='Database of historical p, u, and v from NOAA''s GFS
model';
nc.date=datestr(now,'dd-mmm-yyyy');
etc

Please describe exactly how you created and inserted data into
your .nc file.

Did you try ncdump on your .nc file?

This functions work very good in Matlab, the problems begin when you're trying to create stand-alone application with Matlab.

I just find alternative one. I use cdo program to transform netcdf to ascii ( https://code.zmaw.de/projects/cdo)
The code is: dos(['cdo outputcenter ' fname ' > ASCII_FILE.txt']);

But then you need to reshape files in special way.
Not the very nice solution, but at least it works.
