Function Synopsis

[varargout] = getnc(filin, varn, lims, lev, tim);

Help text

  [varn_out] = getnc(filin, varn, lims, lev, tim);
  [varn_out, lat, lon] = getnc(filin, varn, lims, lev, tim);
  [varn_out, lat, lon, level] = getnc(filin, varn, lims, lev, tim);

  Input variables:

  filin = full pathname of NETCDF file to read
  varn = variable names (can be cell array)
  lims = limits over which to read
  lev = number index of the level you want (optional)
  tim = time index

  Output variables:

  varargout = list of variables to output, in the same
              order as varn
  lat = latitude 
  lon = longitude 
  level = actual levels
