A collection of functions to read GRIB and netCDF files
% CDI_READALL: Read all variables and all their metadata from a file.
% The result is an array of structure.
% X = CDI_READALL(file, nametable)
% -file (mandatory): file to read (NetCDF or GRIB file)
% -nametable (mandatory, not applicable for NetCDF files): non standard GRIB nametable used by SMHI.
% If the nametable is empty or not given, a standard nametable from CDI is used.
% An array of structure with the following fields:
% -varname: variable_name of the variable
% -long_name: long_name of the variable
% -units: units
% -lon: array of longitudes
% -lat: array of latitudes
% -northpole_lon (present if relevant)
% -northpole_lat (present if relevant)
% -levels: array of vertical levels
% -dates: array of timesteps in format
% YYYYMMDD.dec_hour where YYYY is a 4 digit year, MM a 2 digit month, DD a 2
% digit day, and dec_hour the fraction of a 24-hour day
% -data: A 4D matrix of size (XxYxZxT) where X and Y are the grid size,
% Z is the levels number and T is the timestep number.
% If there is one level and one timestep, the output will be a 4D (i.e. 2D) matrix (XxYx1x1)
% If there is one level and several timesteps, the output will be a 4D matrix (XxYx1xT).
% If there are several levels and one timestep, the output will be a 4D (i.e. 3D) matrix (XxYxZx1).
% If there are several levels and several timesteps, the output will be a 4D matrix (XxYxZxT).
% a = cdi_readall('./examples/NA011_0410010600+000H00M','./examples/rcaname.txt');
