1、我在MATLAB的app designer模块设计一个简单的控制界面，有三盏灯，分别用不同开关控制它的颜色变化和频率：
   1）switch1就是左右切换lamp1的颜色；
   2）switch2是切换“On”后闪烁频率为0.5秒的颜色切换；
   上面两个我之前已经运行成功了
   3）lamp3复杂一点，通过输入读取三个值：Temperature(温度)、Humidity（湿度）、WinDSPeed（风速）来列式计算出HCI(人体舒适度指数)，然后在半圆形仪表（HCI）中显示出来，再用if判定一下等级在圆形仪表(HCI_Grade)中显示，若满足相应等级，灯就变色。

MATLAB版本是64位R2016b，操作系统是64位Windows8。请教大神，非常感谢！
界面如下：

2、完整代码如下：
