请问FORTRAN如何提取变量

楼主大人，我用这个工具包读GFS的grib2预报数据
Data.isobaric=double(grib2.data('isobaric1'))/100;%21 level and convert it into hPa
Attempt to reference field of non-structure array.

Error in ncdataset/readdata (line 461)
                array = v.read();

Error in ncdataset/data (line 159)
                    d = obj.readdata(variable);

Error in ncgeodataset/subsref (line 622)
                            B = builtin('subsref',obj,g);

Error in Grib2_read (line 8)
Data.isobaric=double(grib2.data('isobaric1'))/100;%21 level and convert it into hPa


请问怎么用这个工具包读出GFS数据里的变量列表呢？这个variableName一直对不上号

你看看读出的类里面有没有variables，具体的不急的了
