在Matlab GUI界面导入图片,可以使用`imread`函数读取图片,然后使用`imshow`函数在GUI界面上显示图片。以下是一个简单的示例代码:
```matlab
function myGUIFunction(hObject, eventdata, handles)
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% --- Executes on button press in import_button.
function import_button_Callback(hObject, eventdata, handles)
% hObject handle to import_button (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Allow user to select image file
[file, path] = uigetfile({'*.jpg;*.png;*.bmp','Image Files'},'Select an image file');
if isequal(file,0)
return;
end
% Read image file
image_data = imread(fullfile(path,file));
% Display image in GUI
axes(handles.image_axes);
imshow(image_data);
```
在这个示例代码中,`import_button_Callback`函数会弹出一个文件选择对话框,让用户选择要导入的图片文件。然后使用`imread`函数读取图片,使用`imshow`函数在GUI界面中的指定坐标轴上显示图片。
