mdlRTW - Generate code generation data

Required

No

C Syntax

#define MDL_RTW

void mdlRTW(SimStruct *S)

C Arguments

S

SimStruct representing an S-Function block.

MATLAB Syntax

WriteRTW(s)

MATLAB Arguments

s

Instance of Simulink.MSFcnRunTimeBlock class representing the Level-2 MATLAB S-Function block.

Description

This function is called when the Simulink Coder product is generating the model.rtw file. In C MEX S-functions, you can call the following functions that add fields to the model.rtw file:

• ssWriteRTWParameters

• ssWriteRTWParamSettings

• ssWriteRTWWorkVect

• ssWriteRTWStr

• ssWriteRTWStrParam

• ssWriteRTWScalarParam

• ssWriteRTWStrVectParam

• ssWriteRTWVectParam

• ssWriteRTW2dMatParam

• ssWriteRTWMxVectParam

• ssWriteRTWMx2dMatParam

In C MEX S-functions, this function must be enclosed in a #if defined(MATLAB_MEX_FILE) statement.

In Level-2 MATLAB S-functions, use the run-time object's WriteRTWParam method to write custom parameters to the model.rtw file.

Languages

C, C++, MATLAB

C Example

See the S-function sfun_multiport.c in the Simulink model sldemo_msfcn_lms.mdl for an example.

MATLAB Example

See the S-function adapt_lms.m in the Simulink model sfcndemo_sfun_multiport.mdl for an example.
