对于任务，我们必须创建一个程序，根据他们的WBAN ID读取六个特定站点的每日天气数据，并找出特定月份的平均温度值。问题是，文件是由人们无法读取的;它看起来只是胡说八道。我需要的值在标题Tavg下。
该文件如下所示:(请注意，第一个文本块应该是一行标题）
WBAN,YearMonthDay,Tmax,TmaxFlag,Tmin,TminFlag,Tavg,TavgFlag,Depart,DepartFlag,DewPoint,DewPointFlag,WetBulb,WetBulbFlag,Heat,HeatFlag,Cool,CoolFlag,Sunrise,SunriseFlag,Sunset,SunsetFlag,CodeSum,CodeSumFlag,Depth,DepthFlag,Water1,Water1Flag,SnowFall,SnowFallFlag,PrecipTotal,PrecipTotalFlag,StnPressure,StnPressureFlag,SeaLevel,SeaLevelFlag,ResultSpeed,ResultSpeedFlag,ResultDir,ResultDirFlag,AvgSpeed,AvgSpeedFlag,Max5Speed,Max5SpeedFlag,Max5Dir,Max5DirFlag,Max2Speed,Max2SpeedFlag,Max2Dir,Max2DirFlag

这是一个csv文本，逗号分隔值。如果保存为文本文件（比如称之为test.csv），你应该可以用Excel，LibreOffice calc等打开它。使用matlab试试qazxsw poi
