netcdf.open - Open netCDF file
Syntax
ncid = netcdf.open(filename, mode)
[chosen_chunksize, ncid] = netcdf.open(filename, mode,
chunksize)
Description
ncid = netcdf.open(filename, mode) opens
an existing netCDF file and returns a netCDF ID in ncid. mode describes
the type of access to the file and can have any of the following values.
| Value | Description |
|---|
| 'NC_WRITE' | Read-write access |
| 'NC_SHARE' | Synchronous file updates |
| 'NC_NOWRITE' | Read-only access |
You can also specify mode as a numeric value
that can be retrieved usingnetcdf.getConstant.
Use these numeric values when you want to specify a bitwise-OR of
several mode.
[chosen_chunksize, ncid] = netcdf.open(filename, mode,
chunksize) opens an existing netCDF file, specifying an
additional I/O performance tuning parameter, chunksize.
The actual value used by the netCDF library might not correspond
to the input value you specify.
This function corresponds to the nc_open and nc__open functions
in the netCDF library C API. To use this function, you should be familiar
with the information about netCDF contained in the NetCDF
C Interface Guide for version 3.6.2.
Examples
This example opens the example netCDF file included with MATLAB, example.nc.
ncid = netcdf.open('example.nc','NC_NOWRITE');
