用matlab编程 调用标签分别为popupmenu1,edit1,edit2,edit3,axes1等控件完成示波器GUI设计,实现自由输入波形参数(幅度、角频率、相位),选择输出正弦信号或者余弦信号波形,GUI界面如图1所示。请编写“画图”按钮的回调函数。绘图请添加标题“示波器”,横坐标轴“时间t”,纵坐标轴“幅度v”,时间间隔0.02*pi。

Matlab GUI
好的,我知道了。下面是 "画图" 按钮的回调函数代码:
```matlab
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Get the input parameters
amplitude = str2double(get(handles.edit1, 'String'));
angular_freq = str2double(get(handles.edit2, 'String'));
phase = str2double(get(handles.edit3, 'String'));
signal_type = get(handles.popupmenu1, 'Value');
% Calculate the time vector
t = 0:0.02*pi:2*pi;
% Generate the signal
if signal_type == 1
signal = amplitude*sin(angular_freq*t + phase);
else
signal = amplitude*cos(angular_freq*t + phase);
end
% Plot the signal
axes(handles.axes1);
plot(t, signal);
title('示波器');
xlabel('时间t');
ylabel('幅度v');
end
```
这个函数首先获取输入参数(幅度、角频率、相位以及信号类型),然后根据输入参数生成相应的正弦或余弦信号。最后将信号绘制到 axes1 控件上,并添加标题和坐标轴标签。
