I need to call a matlab code from parallel MPI Fortran or C codes running on multiple nodes of a Linux cluster, my understanding is that I can do it through Matlab engine, does that require multiple Matlab licenses or just one?

Hi Shangli,
Does your setup need MATLAB to be installed on each node? Or can all the node access a common MATLAB installation?
If you need to install MATLAB on each node, confirm the license requirements with the Licensing and Install team at MathWorks.
For more information, you may also refer to the documentation for MathWorks Licensing .

Rahul, Thank you for your message. In my case, all the nodes can access a common Matlab installation, I am not sure if I need as many licenses as the number of nodes used. I couldn't find a direct answer in the Matlab licensing link you pointed out. Do you know the answer? On the other hand, I notice that mcc can compile matlab programs to shared libraries, does that require a single or multiple licenses if I am calling the library from a MPI program?
