I am having the interface definitions in c++ files and I would like to use that interfaces in Matlab simulink. So, please suggest whether better to use coder.ceval or legacy code tool ? and how the both are different from each other.

The Legacy Code Tool is generally used for integrating the C or C++ function into Simulink. The functions are generally S-functions which need to be inserted as a Simulink Block in the model. Whereas using coder.ceval and other equivalent commands we can call external C/C++ functions into MATLAB environment. For this Code Generation is used while calling the C/C++ function. It is suggested to use Legacy Code Tool while working with Simulink Models and if working on Building interface between C/C++ code to MATLAB, coder.ceval can be used.
