Add NetCDF schema definitions to NetCDF file
ncwriteschema(filename,schema)
ncwriteschema(filename,schema) creates
or adds attributes, dimensions, variable definitions and group structure
defined in schema to the file filename.
Use ncwriteschema in combination with ncinfo to
create a new NetCDF file based on the schema of an existing file.
You can also use ncwriteschema to add variable
definitions, attributes, dimensions, or group structure to an existing
file.
Note
ncwriteschema does not write variable data.
Use ncwrite to write data to the created variables.
Created unlimited dimensions will have an initial size of 0 until
you write data.
Note
ncwriteschema cannot change the format of
an existing file. It cannot redefine existing variables and dimensions
in filename. If your schema contains attributes,
dimensions, variable definitions, or a group structure that already
exist in the file, writeschema issues a warning
but continues processing.

Create a classic format file with two dimension definitions.
mySchema.Name = '/';
mySchema.Format = 'classic';
mySchema.Dimensions(1).Name = 'time';
mySchema.Dimensions(1).Length = Inf;
mySchema.Dimensions(2).Name = 'rows';
mySchema.Dimensions(2).Length = 10;
ncwriteschema('emptyFile.nc', mySchema);
ncdisp('emptyFile.nc');Create a netcdf4_classic format file to store
a single variable from an existing file. First use ncinfo to
get the schema of the peaks variable from the file. Then use ncwriteschema to
create a NetCDF file, defining the peaks variable. Use ncread to
get the data associated with the peaks variable and then use ncwrite to
write the data to the variable in the new NetCDF file.
myVarSchema = ncinfo('example.nc','peaks');
ncwriteschema('peaksFile.nc',myVarSchema);
peaksData = ncread('example.nc','peaks');
ncwrite('peaksFile.nc','peaks',peaksData);
ncdisp('peaksFile.nc');
