在MATLAB中嵌入Python

Question

我正在尝试将Python2.6嵌入MATLAB（7.12）中。我想嵌入一个用C语言编写的mex文件，这对于使用标量的简单小例子来说很好。但是，如果Numpy（1.6.1）在任何情况下被导入，MATLAB就会崩溃。我之所以这么说，是因为我尝试了很多方法来加载numpy库，包括

1. 在python模块（.py）中：

   from numpy import *
   

2. 在mex文件中使用PyRun_SimpleString：

   PyRun_SimpleString(“from numpy import *”);
   

3. 使用Py_oBject_CallObject调用numpy函数：

最初，我认为这可能是在C中嵌入Numpy的一个问题。但是，当Numpy嵌入到简单的C文件中时，Numpy可以正常工作，这些文件是使用visualstudios2005c编译器通过/MD（多线程）开关从命令行编译的。接下来，我想我只需要在MATLAB中更改make文件，以包含/MD开关。没有这样的运气，墨索普斯.bat使用/MD开关编译。我还手动注释了Numpy init模块中的行，以找到导致MATLAB崩溃的原因。似乎加载任何扩展名为pyd的文件都会导致MATLAB崩溃。在NumPy中加载的第一个这样的文件是多数组.pyd. MATLAB文档描述了如何使用visualstudios调试mex文件，并在下面给出了错误消息。在这一点上，我知道问题是与pyd的内存问题和一些与MATLAB的冲突。有趣的是，我可以使用MATLAB中的系统命令启动python中使用numpy的进程，并且不会生成错误。我将在下面粘贴来自MATLAB的错误消息，然后在visualstudios中粘贴导致MATLAB崩溃的进程的调试输出。但是，我并没有粘贴全部内容，因为第一次机会例外的列表非常长。有没有解决这个整合问题的建议？在

Answer 1

试着从Python方面来解决这个问题：Python是一种很棒的粘合语言，我建议您让Python运行Matlab和C程序。Python有：

1. Numpy公司
2. 幽门
3. Matplotlib库
4. 伊普顿

因此，对于几乎任何现有的Matlab模块来说，这种组合都是一个很好的替代方案。在
