Can't start MATLAB engine

我不知道什么原因...我有两个版本的Matlab R2011a 64位，和R2010b 32位。我使用matlab的第二版本的引擎lib。操作系统windows 7 x64。
根据一些主题，这个问题可能是由多个matlab版本引起的
MATLAB引擎Windows 7问题
但我已从PATH环境变量删除x64 Matlab ...

I don't know what is the reason ... I have two versions of Matlab R2011a 64-bit, and R2010b 32-bit. I use engine lib of second version of matlab. OS windows 7 x64. According to some topics this problem can be caused by multiple matlab versions MATLAB Engine Windows 7 problem but i have deleted x64 Matlab from PATH enviroment variable...

推荐答案

有几件事要试试：

• 确保您的PATH设置为具有Matlab二进制目录的完整路径。例如，64位matlab这是C：\Program Files \MATLAB\R2011a\bin\win64。我不知道为什么你有两个2011a的副本，但我会确认只有一个安装的matlab是在当前路径。


• 确保您使用32位编译器，当使用32位matlab，和64位编译器时使用64位matlab。这是非常重要的。


• 确认您使用的是


• 尝试重新注册Matlab COM 。我不得不这样做2010/2011安装。
  
  
  
  
  • 在linux上，请确保已安装csh。
  
  
  • Make sure your PATH is set to have the full path of the Matlab binary directory. For example, 64bit matlab this is C:\Program Files\MATLAB\R2011a\bin\win64. I'm not sure why you have two copies of 2011a, but I would confirm that only one install of matlab is on the current path.
  • Make sure you are using a 32bit compiler when using 32bit matlab, and 64bit compiler when using 64bit matlab. This is very important.
  • Confirm you are using a compiler that is supported
  • Try re-registering the Matlab COM. I've had to do this for a 2010/2011 install.
    • On linux, make sure csh is installed.
