ss2sf - Subsystem-to-S Function

Convert a subsystem to an s-function via the MATLAB command line.

Typically, you have to right-click on a subsystem, choose Real Time Workshop -> Generate S-Function in order to replace a standard Simulink subsystem with an S-function.
With ss2sf, you can provide a cell array of subsystem paths and the function will replace the specified subsystems with their s-function equivalents.
