wind拉取



%% 从wind拉取
instrumentCodeUni=[instrumentCodeUni;'000300.SH';'000905.SH';'000016.SH'];%加上沪深300，中证500，上证50
instStr='';
for i=1:1:length(instrumentCodeUni)
    if i~=length(instrumentCodeUni)
    str=sprintf('%s,',instrumentCodeUni{i});
    else
    str=instrumentCodeUni{i};   
    end
    instStr=strcat(instStr,str);   
end

w=windmatlab;
[w_wsd_data]=w.wsd(instStr,'pct_chg',num2str(dayUni(1)),num2str(dayUni(end)),'PriceAdj=F');
rateTable=w_wsd_data/100;

save(['./data/','Rate.mat'],'dayUni','instrumentCodeUni','rateTable'); %拉取数据后可以直接的存储成为mat 在matlab中就是这么方便。
