Question

我试图使用R.matlab软件包，但坦率地说我无法启动Matlab服务器。

我在OS X 10.11.5上使用Matlab R2015b。

在R中我得到

> 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

但是在终端中，我确实可以使用matlab命令启动Matlab。

也在终端内

matlab -nodesktop -nosplash -r MatlabServer

结果

Undefined function or variable 'MatlabServer'.

Answer 1

我设法修复它从终端运行matlab。您只需转到用户个人资料~/usr/your_nickame并在任何编辑器中编辑文件 .bash_profile （并保存！）并添加

alias matlab=“/Applications/MATLAB_R2015a.app/bin/matlab”

终端知道matlab的意思，在哪里找到它并执行它。它会使别名永久化。如果从终端

启动服务器，则可以选择此选项

如果你想直接从R启动它，我设法通过设置 matlab 命令运行来使其工作：

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

然后通常的作品：

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