Syntax

void ssSetOptions(SimStruct *S, uint_T options)

Arguments

options

Options. See S-Function Options for available options.

Description

Use in mdlInitializeSizes to specify S-function options.

The options must be joined using the OR operator. For example:

ssSetOptions(S, (SS_OPTION_EXCEPTION_FREE_CODE |
                SS_OPTION_DISCRETE_VALUED_OUTPUT));

Each S-function sets its applicable options at the end of its mdlInitializeSizes method.
