楼主能不能具体一点啊，“tcopulaCL文件里面有没有function tdis_inv 开头，end结尾的内置函数句柄。
没有的话，就是程序漏掉了一些东西。”这个漏掉的东西怎么写出来

大侠，能不能说的具体点啊，这个漏掉的东西怎么改，我改了好多次都不对

在 google 里直接搜索M程序。 http://www.wiley.com/legacy/wileychi/koopbayesian/supp/tdis_inv.m

谢谢

我把这个M程序放进工具箱之后，还是运行不出来，不知道大侠有没有遇到过啊，这是怎么回事呢，十分感谢

supply the gradient in the objective function and set the GradObj option

可是楼主，又告诉我beta_inv这个程序没有，怎么解决啊？
