Can I run matlab on Windows with UI, just that the code runs on remote server?

阅读更多关于 Can I run matlab on Windows with UI, just that the code runs on remote server?

I am using my laptop to run MATLAB and it's very convenient but SLOW. We have strong servers that run MATLAB but it's more convenient for me to run the application with UI on my laptop (as opposed to say running Matlab through command line).

Several options spring to mind, not all of which answer the precise question that you posed. Given that your laptop is Windows, you could do one of these things: Use remote desktop to connect to the server and run MATLAB there

阅读更多关于 Knowing if a remote port forward was successful?

问题 I am trying to setup some reverse ssh tunnels so I can access my home network by bouncing off some server with a public IP. When I run this command: ssh -R :[port_XX]:localhost:22 some_user@my_server Even if "port_XX" is in use, it will still make a successful ssh connection to "my_server".
