以前写的matlab代码，有部分是从txt导数据到matlab里，还有合并矩阵

功能有把txt/excel表导数据到matlab里，还有合并矩阵，还有连mysql数据库

我从以前的代码里找到，不知道这个版本是不是能运行的，但是也差不多就是这样。matlab中总是要转换数据的类型，心好累

load 'X:/work/CN_Univ.mat'

t=dhfetch('S_SHARE_TOTAL','CN_Univ.RIC',datestr(date,'yyyy-mm-dd'));

c=dhfetch('S_SHARE_FREESHARES','CN_Univ.RIC',datestr(date,'yyyy-mm-dd'));

dhfetch('S_SHARE_TOTAL','000001.SZ','2015-10-27')

dhfetch('S_SHARE_TOTAL','000001.SZ',datestr(date,'yyyy-mm-dd'))

for i = 1:length(CN_Univ.RIC)

a=CN_Univ.RIC{i,1};

id(i) = str2num(a(1:6));

end

id=id';

txtFileName = 'X:\work\capitalStock.txt';

fid = fopen(txtFileName,'w+');

for ii = 1:size(Temp,1)

for jj = 1:size(Temp,2)

if ii < size(Temp,1)

if jj == 1

fprintf( fid, '%s\t', Temp{ii,jj});

else

fprintf( fid, '%s\n', Temp{ii,jj});
