python - 关于 pymatbridge

Question

我正在学习如何从 python 脚本执行 Matlab 代码(.m 文件)。所以我已经安装了 pymatbridge 但无法成功。我使用的是 Ubuntu 12.04、Matlab 2013 版和 python 2.7.3。

我已点击链接 http://arokem.github.io/python-matlab-bridge/并粘贴了下面的命令，但收到错误消息，指出意外的关键字参数“host”。

from pymatbridge import Matlab
mlab=Matlab()
mlab=Matlab(matlab='/usr/local/MATLAB/R2013a/bin/matlab', host='192.168.0.1',port=5151)
Traceback (most recent call last): File "", line 1, in TypeError: init() got an unexpected keyword argument 'host'

所以我将命令更改为，

mlab=Matlab(matlab='/usr/local/MATLAB/R2013a/bin/matlab')
mlab.start()

Invalid MEX-file

Error in matlabserver (line 7)
messenger('init', socket_address);

请帮我解决这个问题，因为我是编程新手，也不熟悉 ubuntu。

问候，戈库尔。

出于某种原因，http://arokem.github.io/python-matlab-bridge/ 上的文档与存储库上的 master 分支相比已经过时，并且与发布版本 0.2 相关。此处的文档:https://github.com/arokem/python-matlab-bridge是与当前开发版本相关的版本。

至于你的问题，我认为你需要在你的机器上安装libzmq。在 ubuntu 上，这是通过在终端执行以下命令来完成的:

sudo apt-get install libzmq-dev
