Improve simulation speed with accelerator and rapid accelerator modes

Use Accelerator and Rapid Accelerator modes to achieve faster simulation without changing the model itself. To find out more, see What Is Acceleration?


sim Simulate dynamic system
set_param Set system and block parameter values
Simulink.BlockDiagram.buildRapidAcceleratorTarget Build Rapid Accelerator target for model and return run-time parameter set
Simulink.BlockDiagram.getChecksum Return checksum of model
Simulink.SubSystem.getChecksum Return checksum of nonvirtual subsystem
slbuild Build standalone executable or model reference target for model; except where noted, this function requires a Simulink Coder license
