我有一个具有大量功能的数据集,因此分析相关矩阵变得非常困难.我想绘制一个相关矩阵,我们可以使用dataframe.corr()pandas库中的函数.是否有任何内置函数由pandas库提供以绘制此矩阵？

我收到一个错误:

IllegalArgumentException : Executable name has embedded quote, 
split the arguments 

在运行时

Runtime.getRuntime().exec(cmd, envTokens, file1);

我正在使用Windows7和Java7机器.

相同的代码行适用于其他环境.

建议我一些方法.

我想在java中用它的标记拆分一个字符串.例如;

String s = "A#B^C&D!ased&acdf@Mhj%"
String temp[] = s.split("[#^&!@%]+");

Current output :-
temp[0] = A
temp[1] = B
temp[2] = C
temp[3] = D
temp[4] = ased

output which i want :-
temp[0] = A#
temp[1] = B^
temp[2] = C&
temp[3] = D!
temp[4] = ased&

My current approach of doing is 
  pos =  find the index of the token in string
  pos = add the size of the token in pos
  charAtPos  = getcharfrom string at index pos …
