How can I read and extract Fill Value from netcdf file

I really thanks someone tell me how can I extract fill value, I used following comment it doesn't work. Thanks in advance.

FillValue = ncreadatt (ncfilename, 'PRES', 'FillValue_');

nc {'PRES'}. FillValue_ = ncfloat (99999);

FillValue = ncreadatt( ncfilename, 'PRES', '_FillValue' );

Try this:

I assume that the name of your NetCDF is filename

vinfo = ncinfo(filename) % You can see the struct now
Fill_v = vinfo.Variables.FillValue % extract fill value
