R.matlab-无法启动服务器

我正在尝试使用

R.matlab

包，但坦率地说，我无法启动matlab服务器

我在OSX10.11.5上使用MatlabR2015B

在R之内我得到

> Matlab()
[1] "Matlab: The MATLAB host is 'localhost' and communication goes via port 9999. Objects are passed via the local file system (remote=FALSE). The connection to the MATLAB server is closed (not opened)."
> Matlab$startServer()
[1] 0
sh: matlab: command not found

但在终端中，我确实可以使用

Matlab

命令启动Matlab

也在一个终端内

matlab -nodesktop -nosplash -r MatlabServer

导致

Undefined function or variable 'MatlabServer'.
>>

---

我设法修复它，从终端运行matlab。您只需转到您的用户配置文件

~/usr/your_nickame

并在任何编辑器中编辑文件。bash_profile（并保存！），然后添加

这样终端就知道你们所说的matlab是什么意思，以及在哪里找到它并执行它。它将使别名永久化。如果您是从终端启动服务器，则该选项可用

如果您想直接从R启动，我通过设置matlab命令的运行方式使其工作：

options(matlab="/Applications/MATLAB_R2015a.app/bin/matlab")

然后是通常的工作：

     require(R.matlab)
      Matlab$startServer()
      matlab <- Matlab()
      isOpen <- open(matlab)
   < M A T L A B (R) >

即使经过这么长时间。非常感谢。非常感谢。
