Revert system data types and settings changed during optimization to original state
If the system you are optimizing contains a MATLAB Function block, the optimization replaces the block with a Variant Subsystem, Variant Model block in which one variant contains the original MATLAB Function block and the other variant contains the block with the optimized, fixed-point data types. When you revert a system containing a MATLAB Function block, the variant containing the original MATLAB Function block is set as the active variant.
Similarly, if the system you are optimizing contains a Stateflow® chart, the optimization process first replaces all data types in the chart with
Simulink.NumericType objects. When you revert a system containing a
Stateflow chart, the data type of the
Simulink.NumericType objects are
restored to their original data type, but the
NumericType objects still exist
in the model.
In both of these cases, when you revert your system, the model behaves numerically identically to how it did before the optimization, however, the model is not actually identical to its state before optimization.
