a question with netcdf

[slvester]

Hello everyone,recently I have encoutered a strange question about netcdf;
in matlab;
>nc=netcdf('ncfile');(for example nc=netcdf('NECP_landmask.nc'))
Index exceeds the matrix dimensions
I just want to open the netcdf file ,and even the file is not so big.
I do no know anything abot the question .
the Linux netcdftoolbox I have been installed successful.and the nudump is ok,maybe only the netcdf is not ok
Can you help me?
thaks

According to "NetCDF Toolbox Interface Descriptions":
http://mexcdf.sourceforge.net/netcdf_to ... guide.html

You should define 'mode' when you want to open NetCDF file like follows;
nc=netcdf('ncfile', 'nowrite')

I don't know whether this answer is correct or not, but why not trying?

Thank you hyy!I know you mean.But the question is the same
>nc=netcdf('NCEP_landmask.nc','nowrite')
Index exceeds the matrix dimensions
and even
>nc=netcdf('NCEP_landmask.nc','w')
Index exceeds the matrix dimensions
I don no konw why? I just want to open the nc file,and edit it.
may be the nctoolbox I haven't instlled successful.But everything is ok except the 'netcdf'
help
