Specify by function
Deterministic custom code functions
Model Configuration Pane: Simulation Target
Description
The Specify by function parameter specifies which custom code functions
are deterministic, that is, always producing the same outputs for
the same inputs. This parameter is enabled only when the Deterministic functions parameter is set to By Function. If a
custom code function is specified as deterministic, then a C
Caller or C Function block that calls
that function can be used in a For Each subsystem or with continuous
sample time, and the block is optimized for use in conditional input
branch execution. When a block is optimized for use in conditional
input branch execution, it is executed only if it is in the active
branch of a Switch or Multiport Switch
block, both in simulation and in generated code. See Conditional input branch
execution.
Settings
Specify the names of custom code functions that are deterministic, that is, always producing the same outputs for the same inputs.
- add
Add a name to the list of custom code deterministic functions.
- remove
Remove a name from the list of custom code deterministic functions.
Tip
If you do not see a list of your custom code functions in the Specify by function dialog box, close the dialog box, click Validate custom code, and click Specify by function again.
