是不是要把您安装EMD的目录 保存一下，以后这个EMD文件夹里面的程序就可以直接调用了。用savepath来完成 但是那么多出错的问题没有编译通过，请问您是用什么编译器的，从哪里可以下载，多谢了

我以前安装的时候根本就没出过问题。MATLAB是7.1版，VC++是6.0，按照上面的步骤很顺利。建议楼主也可以尝试运行一个主程序，看看是不是能行。
[ 本帖最后由 zhangnan3509 于 2008-5-9 11:10 编辑 ] 我查了VC中有complex文件，没有后缀，然后我看到一些VC程序，里面写的包含是
#include <complex>
而不是
#include <complex.h>
我尝试复制一个complex文件，并重命名为complex.h，结果提示

这是缺少instfreq函数。以前的帖子里也有类似的问题

现在应该有新的EMD安装的版本，可以重新下载。

关于#include <complex.h>问题的解决？也许是对的，请高手指正
我现在改了一下工具包中src文件夹下的程序代码，而后安装，安装之后只有一个错误提示：D:\Program Files\Microsoft Visual Studio\VC98\INCLUDE\eh.h(32) : fatal error C1189: #error :"eh.h is only for C++!"
查了一下，eh.h是error handle exception文件，用于处理异常抛出问题解决的，应该没有太大关系。
修改后，现在运行您上面的程序没有出错，我把修改后的内容列出来，供大家一起探讨。
原来在src文件夹下的前4个文件，都有这样的包含语句:#include <complex.h>
但是在Vc中是不存在这个头文件的，但是有一个叫做COMPLEX的文件，用VC打开后，发现
Complex是复数类，是一个属于STL的头文件，要包含这种文件，出了include还需要命名空间，所以最后，我把那句include语句修改为：
# include<complex>
using namespace std;
目前运行程序没有大的问题，请各位高手指点！
关于EMD的安装问题探讨
我也在安装EMD遇到类似的问题但现在发现，安装程序里有一些文件本身就有问题！更详细的情况想和你探讨下。
