Automatically infer global variables as function interfaces

Option to automatically populate global variables as function inputs and outputs by running custom code analysis

Since R2022a

Model Configuration Pane: Simulation Target

Description

Specify the behavior of global variables in custom code called by the C Caller block. If you select this option, the C Caller block automatically infers global variables from the custom code on the block interface.

Category: Simulation Target

Settings

off (default) | on

on

Enables automatic addition of global variables from the custom code called by C Caller block. C Caller block treats the global variables in your custom code as global arguments on the block interface. These arguments appear in bold on the Port Specification table.

off

Disables automatic addition of global variables from the custom code called by the C Caller block. From the MATLAB^® command line, use the addGlobalArg function to add or the deleteGlobalArg function to delete global arguments.
