mdlOutputs

Compute the signals that this block emits

Required

Yes

Languages

C, C++

Syntax

#define MDL_OUTPUTSvoid mdlOutputs(SimStruct *S, int_T tid)

Arguments

S

SimStruct representing an S-Function block.

tid

Task ID.

Description

The Simulink®engine invokes this required method at each simulation time step. The method should compute the S-function's outputs at the current time step and store the results in the S-function's output signal arrays.

Thetid(task ID) argument specifies the task running when themdlOutputsroutine is invoked. You can use this argument in themdlOutputsroutine of a multirate S-Function block to encapsulate task-specific blocks of code (seeMultirate S-Function Blocks).

Use theUNUSED_ARGmacro if the S-function does not contain task-specific blocks of code to indicate that thetidinput argument is required but not used in the body of the callback. To do this, insert the line

UNUSED_ARG(tid)

在声明后mdlOutputs.

Note

If you haveSimulink Coder™, when generating code for a noninlined S-function that contains this method, make sure the method is not wrapped in a#if defined(MATLAB_MEX_FILE)statement. For example:

#if defined(MATLAB_MEX_FILE) static void mdlOutputs(SimStruct *S) { /* Add mdlOutputs code here * } #endif

Thedefinestatement makes themdlOutputsmethod available only to a MATLAB®MEX file. If the S-function is not inlined, theSimulink Coderproduct cannot use this method, resulting in link or run-time errors.

Example

For an example of anmdlOutputsroutine that works with multiple input and output ports, seesfun_multiport.c.
