netcdf.open - Open NetCDF data source

Syntax

Description

ncid = netcdf.open(source, mode) opens source, which can be the name of a NetCDF file or the URL of an OPeNDAP NetCDF data source, with the type of access specified by mode. Returns a NetCDF ID in ncid.

mode can have any of the following values.

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 modes.

[chosen_chunksize, ncid] = netcdf.open(source, mode, chunksize) opens source, an existing netCDF data source , specifying the 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 netCDF programming paradigm. See netcdf for more information.

Examples

This example opens the example NetCDF file included with MATLAB, example.nc.

ncid = netcdf.open('example.nc','NC_NOWRITE');
netcdf.close(ncid);
