System Derivatives

Specify external system derivative code

expand all in page

Description

For a model or nonvirtual subsystem that includes the System Derivatives block and a block that computes continuous states, the code generator adds external code, which you specify, to the SystemDerivatives function that it generates. You can specify code for the code generator to add to the declaration, execution, and exit sections of the function code.

Note

If you include this block in a referenced model, the code generator ignores the block for simulation target builds, but processes the block for other system target files.

Parameters

`System Derivatives Function Declaration Code` — Code to add to the declaration section of the generated function

Specify code that you want the code generator to add to the declaration section of the SystemDerivatives function for the model or subsystem.

`System Derivatives Function Execution Code` — Code to add to the execution section of the generated function

Specify code that you want the code generator to add to the execution section of the SystemDerivatives function for the model or subsystem.

`System Derivatives Function Exit Code` — Code to add to the exit section of the generated function

Specify code that you want the code generator to add to the exit section of the SystemDerivatives function for the model or subsystem.
