Pass inputs and read outputs from standalone executable

Hi everyone,

I have a Simulink model which uses also some user defined matlab functions to make some calculations. In the next step I'm generating code from that Simulink model.

Then I want to use the executable along with my C program to run some simulations in an environment completely independent from Matlab or Simulink. How can I pass inputs to and read outputs from the executable?

Unfortunately, moving my C code to Simulink and using Simulink as a simulation engine is not an option.

Thanks in advance.
