netcdf.inqFormat

Determine format of NetCDF file

Syntax

format = netcdf.inqFormat(ncid)

format = netcdf.inqFormat(ncid) returns the format for the file specified by NetCDF file identifier, ncid.

ncid

Identifier of a NetCDF file, returned by netcdf.create or netcdf.open, or of a NetCDF group, returned by netcdf.defGrp.

format

Character vector that specifies the format of the NetCDF file. Returned values include:

Format	Description
`'FORMAT_CLASSIC'`	Classic format — Original NetCDF format, used by all NetCDF files created between 1989 and 2004
`'FORMAT_64BIT'`	Classic format, 64–bit — Original format with 64–bit addressing capability to allow creation and access of much larger files.
`'FORMAT_NETCDF4'`	Enhanced model, HDF5-based — Introduced in 2008, NetCDF, version 4, extends the classic model and is based on HDF5.
`'FORMAT_NETCDF4_CLASSIC'`	Classic model, HDF5-based — Introduced in 2008, NetCDF, version 4, implements classic model but is based on HDF5.

This example opens the sample NetCDF file and determines the format.

ncid = netcdf.open('example.nc','NOWRITE');
fmt = netcdf.inqFormat(ncid)

format =

FORMAT_NETCDF4

netcdf.close(ncid);

This function corresponds to the nc_inq_format function in the NetCDF library C API.
