回答： Artem V 2018-6-28

Hello! Help me please! I try to use 3d graphics (ogre3d) to visualize calculations in s-function. I experiment with standard s-function timestwo. I have added in it application Win32 which simply displays a window with simple object (It doesn't depend on calculations of s-function). Code of s-function natash.cpp:

#define S_FUNCTION_NAME  natash
#define S_FUNCTION_LEVEL 2
#include "simstruc.h"
#include "Ogre\ExampleApplication.h";
class Example1 : public ExampleApplication
{
public:
void createScene()
{
  Ogre::Entity* ent =
mSceneMgr->createEntity("MyEntity","tiphak..mesh");
Ogre::SceneNode* node = mSceneMgr->createSceneNode("Node1");
mSceneMgr->getRootSceneNode()->addChild(node);
node->attachObject(ent);
node->setPosition(10,0,0);
Ogre::Entity* ent2 = mSceneMgr->createEntity("MyEntity2","Sinbad.mesh");
Ogre::SceneNode* node2 = mSceneMgr->createSceneNode("Node2");
node->addChild(node2);
node2->setPosition(0,10,20);
node2->attachObject(ent2);
}
};
int WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT)
{
Example1 app;
app.go();
return 0;
}
static void mdlInitializeSizes(SimStruct *S)
{
    ssSetNumSFcnParams(S, 0);
    if (ssGetNumSFcnParams(S) != ssGetSFcnParamsCount(S)) {
        return; /* Parameter mismatch will be reported by Simulink */
    }
      if (!ssSetNumInputPorts(S, 1)) return;
      ssSetInputPortWidth(S, 0, DYNAMICALLY_SIZED);
      ssSetInputPortDirectFeedThrough(S, 0, 1);
      if (!ssSetNumOutputPorts(S,1)) return;
      ssSetOutputPortWidth(S, 0, DYNAMICALLY_SIZED);
      ssSetNumSampleTimes(S, 1);
            ssSetSimStateCompliance(S, USE_DEFAULT_SIM_STATE);
            ssSetOptions(S,
                   SS_OPTION_WORKS_WITH_CODE_REUSE |
                   SS_OPTION_EXCEPTION_FREE_CODE |
                   SS_OPTION_USE_TLC_WITH_ACCELERATOR);
  }
    static void mdlInitializeSampleTimes(SimStruct *S)
  {
      ssSetSampleTime(S, 0, INHERITED_SAMPLE_TIME);
      ssSetOffsetTime(S, 0, 0.0);
      ssSetModelReferenceSampleTimeDefaultInheritance(S); 
  }
    static void mdlOutputs(SimStruct *S, int_T tid)
  {
      int_T             i;
      InputRealPtrsType uPtrs = ssGetInputPortRealSignalPtrs(S,0);
      real_T            *y    = ssGetOutputPortRealSignal(S,0);
      int_T             width = ssGetOutputPortWidth(S,0);
      for (i=0; i<width; i++) {
                    *y++ = 2.0 *(*uPtrs[i]); 
      }
  }
    static void mdlTerminate(SimStruct *S)
  {
  }
#ifdef  MATLAB_MEX_FILE    /* Is this file being compiled as a MEX-file? */
#include "simulink.c"      /* MEX-file interface mechanism */
#else
#include "cg_sfun.h"       /* Code generation registration function */
#endif

I do mex with it (with include files and liblaries):

mex -IC:\OgreSDK_vc9_v1-7-2\include -IC:\OgreSDK_vc9_v1-7-2\boost_1_44 -LC:\OgreSDK_vc9_v1-7-2\boost_1_44\lib -LC:\OgreSDK_vc9_v1-7-2\lib -LC:\OgreSDK_vc9_v1-7-2\lib\debug natash.cpp -lOgreMain_d -lOIS_d -llibboost_thread-vc90-mt-1_44 -llibboost_date_time-vc90-mt-1_44

It is compiled successfully. When I use s-function, it increases a signal in 2 times, but doesn't deduce any graphic window. I don't understand why.

I thank for any answer.

For testing, I would recommend Kaustubha's approach for creating an instance of "Example1" and then trying to use it. For the bigger project, I would recommend that you:

Make a "PWork" vector, which is a list of pointers in the S-function that persist in between calls to "mdl*" functions.
In "mdlStart" use "new" to dynamcially create an instance of "Example1" and use the "PWork" vector as a handle so that you can access the instance of "Example1" in other "mdl" functions.
In "mdlOutputs", access the "PWork" vector and call ".go()" "create_scene", or whatever, (I don't know much about Ogre...)
In "mdlTerminate", call get the instance of "Example1" out of the "PWork" vector and use "delete" to clean up any memory that was allocated.

Find the exact line number that causes the shutdown and investigate possible issues with that.

WinMain is not executed by the S-function - in order for the application to run, you must execute the code:

Example1 app;
app.go();

from one of the S-function methods (I recommend mdlOutputs).

They return the same paths...

When I build exe in Visual Studio, Visual Studio creat the exe in OgreSDk\bin\debug. There are many dll files in that folder. Without them it doesn't work. And it does not work If I transfer all it to other folder...

I added Ogre in the system path:

Now, when I try to run mdl, I have an error (Matlab has encountered an internal problem and need to close)...

And if I open mex-file at the Dependency Walker, I have the folowing dwi:

there are not ogre dll's...

I have the same error "Matlab.....must be closed". I have decided to try to use OpenGL for visualization, have followed an example from the textbook (for this purpose it is not required any additional installation). But I have the same error...(!!!!!!)

Source file of the exemple http://depositfiles.com/files/6wju89zqr I use mex -g test_vis.cpp user32.lib gdi32.lib glu32.lib opengl32.lib

This example doesn't work for all or only at me?

In mdlInitializeSizes, you need to add:

ssSetNumPWork(S, 1);

Also, here are some tips to debug S-functions: http://www.mathworks.com/help/toolbox/simulink/sfg/bq2rjeu-1.html

Natalia 2011-4-28

if I add ssSetNumPWork(S, 1);

I have a new error:

Error in 'timo/S-Function' while executing C MEX S-function 'natash', (mdlOutputs), at time 0.0.
