基于Matlab给出了sina即时股票数据获取分析的算法，便于用户开展数据获取和分析工作。

代码如下：

function stockinfo = queryprice(stocktype, stockid)

%stocktype 股票类型：sh和sz

%stockid 股票编码：

url = sprintf('=%s%d', stocktype, stockid);

[sourcefile, status] = urlread(url);

if (~status)

disp('无法获取数据');

else

%取出字符串

str = javaObject('java.lang.String', sourcefile);

str = str.replaceAll('var ', '');

strs = str.split('=');

str = strs(2);

str = str.replaceFirst('"', '{''');

str = str.replaceFirst('"', '''};');

str = str.replaceAll(',', ''', ''');

str = strcat('stock=', char(str));

eval(str);

stockinfo = {};

stockinfo.name = stock(1);

stockinfo.today_start_price = str2double(stock(2));

stockinfo.yestoday_end_price = str2double(stock(3));

stockinfo.current_price = str2double(stock(4));

stockinfo.today_highest_price = str2double(stock(5));

stockinfo.today_lowest_price = str2double(stock(6));

stockinfo.today_first_buy_price = str2double(stock(7));

stockinfo.today_first_sale_price = str2double(stock(8));

stockinfo.today_success_stock_mount = str2double(stock(9))/100;

%单位：手

stockinfo.today_success_money = str2double(stock(10));

%单位：万

stockinfo.today_first_buy_price = str2double(stock(11));

stockinfo.today_first_sale_price = str2double(stock(12));

stockinfo.buy_stock_mount1 = str2double(stock(13)) / 100;

%单位：手

stockinfo.buy_stock_price1 = str2double(stock(14));

%单位：万

stockinfo.buy_stock_mount2 = str2double(stock(15));

stockinfo.buy_stock_price2 = str2double(stock(16));

stockinfo.buy_stock_mount3 = str2double(stock(17));

stockinfo.buy_stock_price3 = str2double(stock(18));

stockinfo.buy_stock_mount4 = str2double(stock(19));

stockinfo.buy_stock_price4 = str2double(stock(20));

stockinfo.buy_stock_mount5 = str2double(stock(21));

stockinfo.buy_stock_price5 = str2double(stock(22));

stockinfo.sale_stock_mount1 = str2double(stock(23));

stockinfo.sale_stock_price1 = str2double(stock(24));

stockinfo.sale_stock_mount2 = str2double(stock(25));

stockinfo.sale_stock_price2 = str2double(stock(26));

stockinfo.sale_stock_mount3 = str2double(stock(27));

stockinfo.sale_stock_price3 = str2double(stock(28));

stockinfo.sale_stock_mount4 = str2double(stock(29));

stockinfo.sale_stock_price4 = str2double(stock(30));

stockinfo.date = stock(31);

stockinfo.time = stock(32);

end

end

示例使用：

info = queryprice('sh', 601006)  %大秦铁路

结果为：

info =
