How to do a system call from simulink?

I would like to embed a C executable in a Matlab Simulink block. The example C files are attached. This has a simple function that calculates sum of two numbers. Does the exe need special inputs/outputs to work with Simulink?, also how to use system call to execute the .exe file within simulink block.

Hello Gunasheela

It is not straight forward to do a system call from Simulink. However, since you have the C-code available I suggest to build a MEX Function from it. A starting point to learn how this works can be Create a Basic C MEX S-Function - MATLAB & Simulink (mathworks.com) or Build C MEX Function - MATLAB & Simulink (mathworks.com)

Good luck, best wishes
