好的,我可以帮你回答这个问题。以下是一个简单的MATLAB GUI代码实现,可以让用户选择要显示的不同波形,并将其绘制在图形窗口中。
```matlab
function wave_gui
% create a GUI to display different types of waves
% create the GUI figure
fig = figure('Visible', 'off', 'Position', [360, 500, 450, 285]);
% create the UI controls
bg = uibuttongroup(fig, 'Position', [0.05 0.5 0.9 0.4]);
sin_button = uicontrol(bg, 'Style', 'radiobutton', 'String', 'Sine Wave', ...
'Position', [20 100 100 20], 'HandleVisibility', 'off');
square_button = uicontrol(bg, 'Style', 'radiobutton', 'String', 'Square Wave', ...
'Position', [20 70 100 20], 'HandleVisibility', 'off');
tri_button = uicontrol(bg, 'Style', 'radiobutton', 'String', 'Triangle Wave', ...
'Position', [20 40 100 20], 'HandleVisibility', 'off']);
plot_button = uicontrol(fig, 'Style', 'pushbutton', 'String', 'Plot Wave', ...
'Position', [180 20 90 25], 'Callback', @plot_wave);
% set the default wave type to sine wave
wave_type = 'sine';
% make the GUI visible
fig.Visible = 'on';
% function to plot the selected wave
function plot_wave(~, ~)
% get the selected wave type from the radio buttons
if sin_button.Value
wave_type = 'sine';
elseif square_button.Value
wave_type = 'square';
elseif tri_button.Value
wave_type = 'tri';
end
% generate the selected wave
switch wave_type
case 'sine'
x = linspace(0, 2*pi, 1000);
y = sin(x);
case 'square'
x = linspace(0, 2*pi, 1000);
y = square(x);
case 'tri'
x = linspace(0, 2*pi, 1000);
y = sawtooth(x, 0.5);
end
% plot the wave
plot(x, y);
xlabel('x');
ylabel('y');
% set the axis limits
xlim([0 2*pi]);
ylim([-1.2 1.2]);
% set the title
title(['Selected Wave: ' wave_type]);
end
end
```
这个GUI界面中,有三个单选按钮,可以选择要显示的不同波形类型。用户可以单击“绘制波形”按钮来绘制所选波形。在这个例子中,我们使用了MATLAB自带的`sine`、`square`和`tri`函数来生成不同类型的波形。你也可以使用自己的函数来生成波形。
