好的,这里是完整的 MATLAB 程序代码,你可以直接复制粘贴到 MATLAB 编辑器中运行:
```
classdef TemperatureControlApp < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
EditFieldLabel matlab.ui.control.Label
EditField matlab.ui.control.NumericEditField
Lamp matlab.ui.control.Lamp
end
% Callbacks that handle component events
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
% 设置 Lamp 初始颜色为蓝色
app.Lamp.Color = [0 0 1];
end
% Value changed function: EditField
function EditFieldValueChanged(app, event)
% 获取用户输入的温度值
temperature = app.EditField.Value;
% 调用函数来更新 Lamp 控件的颜色
updateLampColor(app, temperature);
end
end
% App initialization and construction
methods (Access = private)
% Create UIFigure and components
function createComponents(app)
% Create UIFigure
app.UIFigure = uifigure;
app.UIFigure.Position = [100 100 640 480];
app.UIFigure.Name = 'Temperature Control App';
% Create EditFieldLabel
app.EditFieldLabel = uilabel(app.UIFigure);
app.EditFieldLabel.HorizontalAlignment = 'right';
app.EditFieldLabel.Position = [256 240 60 22];
app.EditFieldLabel.Text = '温度:';
% Create EditField
app.EditField = uieditfield(app.UIFigure, 'numeric');
app.EditField.ValueChangedFcn = createCallbackFcn(app, @EditFieldValueChanged, true);
app.EditField.Position = [331 240 100 22];
% Create Lamp
app.Lamp = uilamp(app.UIFigure);
app.Lamp.Position = [293 163 50 50];
end
end
% Methods that update and manage app state
methods (Access = private)
% Function to update Lamp color based on temperature
function updateLampColor(app, temperature)
if temperature < 0
app.Lamp.Color = [0 0 1]; % 蓝色
elseif temperature >= 0 && temperature < 25
app.Lamp.Color = [0 1 0]; % 绿色
elseif temperature >= 25 && temperature < 50
app.Lamp.Color = [1 1 0]; % 黄色
else
app.Lamp.Color = [1 0 0]; % 红色
end
end
end
% App creation and deletion
methods (Access = public)
% Construct app
function app = TemperatureControlApp
% Create UIFigure and components
createComponents(app)
% Register the app with App Designer
registerApp(app, app.UIFigure)
% Execute the startup function
runStartupFcn(app, @startupFcn)
% Show the figure after all components are created
app.UIFigure.Visible = 'on';
end
% Code that executes before app deletion
function delete(app)
% Delete UIFigure when app is deleted
delete(app.UIFigure)
end
end
end
```
在 MATLAB 编辑器中运行该程序,即可看到一个简单的 GUI 界面,包含一个 Edit Field 和一个 Lamp 控件。输入温度值后,Lamp 控件的颜色会根据温度值的变化而改变。
希望这个完整的程序代码对你有所帮助!
