### 日志
2021.12.05： 更新初版模型。

2021.12.06: 更新ert_main.c。运行Calc_Test_Model.bat，运行生成的exe查看运算结果。

2021.12.16：如何修改ert_main.c？
```C
  /* Attach rt_OneStep to a timer or interrupt service routine with
   * period 1.0 seconds (the model's base sample time) here.  The
   * call syntax for rt_OneStep is
   *
   * 将 rt_OneStep取消注释。
   */
  rt_OneStep(Calc_Test_Model_M);
```
然后增加输入输出显示，修改rt_OneStep的实现：
```C
  OverrunFlag = true;

  /* Save FPU context here (if necessary) */
  /* Re-enable timer or interrupt here */
  int32_T Input_A = 1;
  int32_T Input_B = 2;
  /* Step the model */
  while(1)
  {
   /* Pass input data */
  Calc_Test_Model_U_Input_A = Input_A;
  Calc_Test_Model_U_Input_B = Input_B; 
  Calc_Test_Model_step(Calc_Test_Model_M, Calc_Test_Model_U_Input_A,
                       Calc_Test_Model_U_Input_B, &Calc_Test_Model_Y_sum,
                       &Calc_Test_Model_Y_sub, &Calc_Test_Model_Y_mul,
                       &Calc_Test_Model_Y_div, &Calc_Test_Model_Y_sum_gain);
  printf("Input_A: %ld , Input_B: %ld\n\n"
"sum: %ld\n\n"
"sub: %ld\n\n"
"mul: %ld\n\n"
"div: %lf\n\n"
"sum_gain: %ld\n\n"
,
Calc_Test_Model_U_Input_A,
Calc_Test_Model_U_Input_B,
Calc_Test_Model_Y_sum,
Calc_Test_Model_Y_sub,
Calc_Test_Model_Y_mul,
Calc_Test_Model_Y_div,
Calc_Test_Model_Y_sum_gain); 
Input_A++;
Input_B++;
sleep(1);                    
  }
  /* Get model outputs here */
```
