请问simulink代码如何生成2020a？

首先建立一个简单的模型






进行一下设置
















快捷键 ctrl+B ,编译

此时生成的代码:




/*
* File: untitled.c
*
* Code generated for Simulink model 'untitled'.
*
* Model version                  : 1.0
* Simulink Coder version         : 9.3 (R2020a) 18-Nov-2019
* C/C++ source code generated on : Sun Jul 19 21:00:16 2020
*
* Target selection: ert.tlc
* Embedded hardware selection: Intel->x86-64 (Windows64)
* Code generation objectives: Unspecified
* Validation result: Not run
*/


#include "untitled.h"
#include "untitled_private.h"


/* External inputs (root inport signals with default storage) */
ExtU_untitled_T untitled_U;


/* External outputs (root outports fed by signals with default storage) */
ExtY_untitled_T untitled_Y;


/* Real-time model */
RT_MODEL_untitled_T untitled_M_;
RT_MODEL_untitled_T *const untitled_M = &untitled_M_;


/* Model step function */
void untitled_step(void)
{
  /* Outport: '/Out1' incorporates:
   *  Inport: '/In1'
   *  Inport: '/In2'
   *  Sum: '/Sum'
   */
  untitled_Y.Out1 = untitled_U.In2 + untitled_U.In1;
}


/* Model initialize function */
void untitled_initialize(void)
{
  /* (no initialization code required) */
}


/* Model terminate function */
void untitled_terminate(void)
{
  /* (no terminate code required) */
}


/*
* File trailer for generated code.
*
* [EOF]
*/






有用的:


void untitled_step(void)
{
  /* Outport: '/Out1' incorporates:
   *  Inport: '/In1'
   *  Inport: '/In2'
   *  Sum: '/Sum'
   */
  untitled_Y.Out1 = untitled_U.In2 + untitled_U.In1;
}
参数修改

参数配置

• 以下几张图的位置有变,以上一张为准
  
  

输入设置为:






通过上方按钮添加向相应参数和信号






输出设置为:






参数k设置为:






注: 参数K要有初始值





参数关联

双击连线:更改为之前的,并右键设置property















k直接填就行




编译完后,最终效果:
