emd工具箱的安装问题

whapril

实在不好意思开新帖来发这个问题。
搜索并浏览过往的很多相关的帖子，但还是没有找到我这个问题的解决办法，自己有心去解决，但限于能力有限，效果甚微。不得以在此求助。

emd的工具箱，参考xray的帖子http://forum.vibunion.com/thread-55430-1-1.html下了相应的pack_emd的压缩包，解压放到matlab的toolbox目录下（放哪应该无所谓，只要路径加到matlab里就行了吧），再按照帖子http://forum.vibunion.com/thread-40562-1-33.html中9楼的办法，分别进行了三步安装（先装了vc++6.0）；1，mbuild -setup ；2，mex -setup，均可以成功，但第3步，install_emd时，提示：
>> install_emd
??? Undefined function or variable 'install_emd'.

未定义的函数或变量，这个步骤的意思是什么？

请高人们解答，谢谢！

N=100;
n=1:N;
fs=1000;
t=n/fs;
fx=10;
fy=50;
x=cos(2*pi*fx*t);
y=10*cos(2*pi*fy*t);
z=x+y;
data=z;
%plot(z),grid
emd(data)
运行以上代码，报以下错误。路径已经加入。
??? Undefined function or method 'emd' for input arguments of type 'double'.

Error in ==> Untitled3 at 12
emd(data)

以前的高手们都不在了，还是现在的新人们都不热情了，异或是我的问题太简单了？
谁能帮我解答一下？

好了，问题解决了，
刚运行前面那个程序还是以前的错误，然后再试了试install_emd,突然就可以了。
将文件夹名称emd改成别的了，不知是不是这个原因。

Some errors occurred during compilation. See details above.

Installation complete. Run index_emd for a list of functions.

IMPORTANT: After running INSTALL_EMD you must run the "savepath" command to save the installation
but be careful that if you previously removed parts of the path (using e.g. the "rmpath" command)
these will be permanently removed after you run "savepath"

我是按照这个装的，安装之后跟楼主3的结果是一样的，可是开始菜单里面工具箱还是没有EMD啊？这个工具箱要怎么用啊？
谢谢了啊！！！

按照set path的方法加入路径后，运行install_emd，出现了如下的错误：
