Converting a Simulink Model to a Symbolic Representation

The documentation of the Symbolic Math Toolbox describes how to generate Simulink models from symbolic math expressions. Is there also software that goes the other way: starting with a Simulink model, generate a symbolic math function?

Thanks!

You could

• Create a Simulink model and simulate it
• Either linearize it (Control System Toolbox I believe)
• Or use the simulation input and output data to do system identification with System Identification Toolbox
• As a result you would have a system behaviour that can be written as a symbolic representation
