Matlab 如何从Yahoo上读取免费数据并画图

我也遇到了相同的问题，取深市的股票都正常，但是有些就是说取不到月份，奇怪

>> c=yahoo

c =

  yahoo with properties:

     url: 'http://download.finance.yahoo.com'
      ip: []
    port: []

>> fetch(c,'600680.ss')
Error using datenum (line 178)
DATENUM failed.

Error in yahoo/fetch>DateNA2NaN (line 571)
  tmpdat = datenum(dt(j));

Error in yahoo/fetch (line 259)
        tmpd{j} = DateNA2NaN(tmpd{j});

Caused by:
    Error using datevec (line 212)
    Failed to lookup month of year.

超级不错，我跟你这个学习到了不少啊
