matlabgui界面导入图片

你可以使用MATLAB中的`imread`函数来读取图像,并将其显示在GUI界面上。以下是一个简单的示例代码:
```matlab
function gui_Callback(hObject, eventdata, handles)
% hObject handle to your GUI object
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Choose default command line output for your GUI
handles.output = hObject;
% Read and display image
[filename, pathname] = uigetfile({'*.jpg;*.jpeg;*.png;*.bmp;*.gif','All Image Files';'*.*','All Files'},'Select an Image');
if isequal(filename,0) || isequal(pathname,0)
return
else
image = imread(fullfile(pathname, filename));
axes(handles.axes1);
imshow(image);
end
% Update handles structure
guidata(hObject, handles);
```
在这个示例中,我们使用了`uigetfile`函数来打开一个文件选择对话框,让用户选择要导入的图像文件。然后,我们使用`imread`函数来读取图像文件,将其存储在`image`变量中,并使用`imshow`函数将其显示在GUI界面上的`axes1`坐标轴上。
请注意,在使用`imshow`函数显示图像之前,需要先将`axes1`坐标轴设置为当前坐标轴。你可以通过在GUI设计器中选择`axes1`坐标轴,然后在“属性检查器”中将`Tag`属性设置为“axes1”,或者在代码中使用`handles.axes1`来获取该坐标轴的句柄。
