顶 谢谢楼主啊

Thanks, it is good.

请问一下啊 为什么我按照pdf里的这个[out,ordata]=pot(dan,15,[],[])命令运行会出现以下的情况啊 别的命令没问题啊

在Matlab的toolbox文件夹中放上解压的EVIM后，在MATLAB的菜单中添加文件夹Evim的路径，这样就可以使用了。你的错误在于没有调到需要的程序，故报错。Matlab能否调用到Evim的程序，用help emplot.m 即知。

谢谢楼主！！！！！！！！！！！！

我在使用中也出现了这个问题，但是我设置了路径啊，evim包里的软件应该都可以找到的，请问您后来是怎么解决这个问题的？
