MATLAB 之 App designer 小白学习(二).pdf
好的,下面是一个简单的Matlab App Designer程序,可以将笛卡尔坐标系转换为极坐标系,或将极坐标系转换为笛卡尔坐标系:
1. 创建一个新的Matlab App Designer程序
2. 添加两个输入框和一个按钮,用于输入坐标和进行转换
3. 设置输入框的属性,使其可以接受数字输入
4. 在按钮的回调函数中编写转换代码
5. 运行程序并测试
以下是示例代码:
```matlab
classdef CoordinateConverter < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
CartesianEditField matlab.ui.control.NumericEditField
PolarEditField matlab.ui.control.NumericEditField
ConvertButton matlab.ui.control.Button
end
% Callbacks that handle component events
methods (Access = private)
% Button pushed function: ConvertButton
function ConvertButtonPushed(app, event)
% Get the input value from the Cartesian edit field
x = app.CartesianEditField.Value;
% Convert Cartesian to polar coordinates
[theta, rho] = cart2pol(x(1), x(2));
% Update the polar edit field with the new values
app.PolarEditField.Value = [theta, rho];
end
end
% App initialization and construction
methods (Access = private)
% Create UIFigure and components
function createComponents(app)
% Create UIFigure
app.UIFigure = uifigure;
app.UIFigure.Position = [100 100 307 171];
app.UIFigure.Name = 'Coordinate Converter';
% Create CartesianEditField
app.CartesianEditField = uieditfield(app.UIFigure, 'numeric');
app.CartesianEditField.Position = [28 83 115 22];
% Create PolarEditField
app.PolarEditField = uieditfield(app.UIFigure, 'numeric');
app.PolarEditField.Position = [167 83 115 22];
% Create ConvertButton
app.ConvertButton = uibutton(app.UIFigure, 'push');
app.ConvertButton.ButtonPushedFcn = createCallbackFcn(app, @ConvertButtonPushed, true);
app.ConvertButton.Position = [121 24 70 22];
app.ConvertButton.Text = 'Convert';
% Create CartesianLabel
CartesianLabel = uilabel(app.UIFigure);
CartesianLabel.HorizontalAlignment = 'right';
CartesianLabel.Position = [28 112 60 22];
CartesianLabel.Text = 'Cartesian';
% Create PolarLabel
PolarLabel = uilabel(app.UIFigure);
PolarLabel.HorizontalAlignment = 'right';
PolarLabel.Position = [167 112 33 22];
PolarLabel.Text = 'Polar';
end
end
% App startup and termination
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
end
end
% Component initialization and construction
methods (Access = public)
% Construct app
function app = CoordinateConverter
% Create and configure 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
end
end
```
这个程序只实现了笛卡尔坐标系到极坐标系的转换,如果需要实现极坐标系到笛卡尔坐标系的转换,只需要在回调函数中调用`pol2cart`函数。
