Expectations, Let’s Interact
▪ Leiv: why does MATLAB index start at 1?
▪ Samuel: See something about Statefow
▪ Michael: why should I spend several thousands, when there is FOSS?
▪ Varin: why do you develop new versions, what is the future of MATLAB?
▪ Manish: I have used Git and Stateflow together, I am unsure as to why this
combination does not work as good as Git directly from terminal
▪ Nicola: we heard in the lecture that more an more C code is generated,
what proportion of the C code is automatically generated, what’s the trend?
▪ Friedrich: how could you use cloud computing from MATLAB, like AWS

Example Activities around Code Generation
▪ Incremental model elaboration ensuring the model is “embedded
application aware”
▪ Defining data representation
– simulation vs. code generation behaviour
▪ Generating code
▪ Automating build processes
▪ Integrating external code with generated code
▪ Setting up generated code to interface with components in the run-time
environment
▪ Verifying the generated code

Concluding Remarks
▪ Identify the problem you are trying to solve
▪ “Rule of Two”
▪ Use models to generate production code
▪ Models are the sole source of truth
▪ Use the transition as a learning opportunity
▪ Focus on design instead of coding
▪ Integrate the development process
▪ Designate a champion
▪ Have a long-term vision
▪ Partner with tools suppliers
