netcdf.inqVarFletcher32

Fletcher32 checksum setting for NetCDF variable

Syntax

setting = netcdf.inqVarFletcher32(ncid,varid)

Description

setting = netcdf.inqVarFletcher32(ncid,varid) returns the Fletcher32 checksum setting for the NetCDF variable specified by varid in the file or group specified by ncid.

Input Arguments

`ncid`	Identifier for NetCDF file, returned by `netcdf.create` or `netcdf.open`, or group, returned by `netcdf.defGrp`.
`varid`	Identifier of NetCDF variable.

Output Arguments

setting

Character vector specifying whether the Fletcher32 checksum is turned on for the specified variable. netcdf.inqVarFletcher32 returns 'FLETCHER32' or 'NOCHECKSUM'.

'FLETCHER32' — If the checksum is turned on for the variable.
'NOCHECKSUM' — Otherwise.

Examples

This example opens the sample NetCDF file and gets information about the checksum setting for a variable.

ncid = netcdf.open('example.nc','NOWRITE');
varid = netcdf.inqVarID(ncid,'temperature');
setting = netcdf.inqVarFletcher32(ncid,varid);
netcdf.close(ncid);
