4 Guidelines for Writing C MEX S-Functions

4-26

rtY.Out1 = rtb_buffer2;

/* S-Function Block: <Root>/S-Function1 */

{

real_T *xData = &rtP.S_Function1.XData[0];

real_T *yData = &rtP.S_Function1.YData[0];

int_T idx;

idx = GetDirectLookupIndex(xData, 5, rtb_Sine_Wave);

rtb_buffer2 = yData[idx];

}

/* Outport Block: <Root>/Out2 */

rtY.Out2 = rtb_buffer2;

}

/* Perform model update */

void MdlUpdate(int_T tid)

{

/* (no update code required) */

}

/* Terminate function */

void MdlTerminate(void)

{

/* (no terminate code required) */

}

#include “sfun_directlook_ex.reg”

/* [EOF] sfun_directlook_ex.c */

This is the code that is

inlined for the bottom

S-function block i n the

sfun_directlook_ex

model.
