如果我正确理解你的问题，你应该集成到已编译的EXE。为此，请查看

- MATLAB Compiler SDK [ ^ ]

- 选择语言 - C / C ++ ,. NET或Java [ ^ ]

I use process start function to execute the exe file. How can I load the data computed from that exe file back to c#? Thanks

If I understand your question correctly, you should integrate to the compiled EXE. For that, have a look at
- MATLAB Compiler SDK[^]
- Choosing a Language – C/C++, .NET, or Java[^]
