在GUI中存储工作区变量以供其他按钮使用. MATLAB GUI [英] Storing workspace variable in GUI for use by other push buttons. MATLAB GUI

问题描述

我刚刚开始使用GUIDE制作基本的GUI，到目前为止，我有一个按钮可以用来调用我先前编写的名为sortData.m的.m文件

I have just started making a basic GUI with GUIDE, so far I have one push button that I am using to call a .m file I wrote earlier called sortData.m

当在GUI外部运行时，sortData.m会将一个名为合并"的矩阵放入工作区，但是当我在GUI中运行sortData.m时，什么都不会发生.

When run outside of the GUI, sortData.m puts a matrix called "merge" into the workspace, but when I run sortData.m inside the GUI nothing happens.

我需要合并"存储在某个位置，以便我的下一个按钮可以使用它来输出图形...该怎么办?谢谢

I need "merge" to get stored somewhere so that my next push button can use it to output figures... how can this be done? Thanks

% --- Executes on button press in pushbutton1.
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)
sortData

推荐答案

1. 修改sortData->使其成为函数，方法是将其添加为第一行:

1. modify sortData-> make it a function by adding this as the first line:

function merge = sortData(..)

function merge = sortData(..)

修改回调:

功能pushbutton1_Callback(hObject，eventdata，handles) 合并= sortData handles.merge =合并 guidata(hObject，handles);

function pushbutton1_Callback(hObject, eventdata, handles) merge = sortData handles.merge = merge guidata(hObject, handles);

随后，在获取handles-struct的任何回调中，您可以使用 handles.merge 检索数据. 查看文档以获取有关数据共享的更多信息，请参见(例如):

later, within any callback that gets the handles-struct, you can retrieve the data with handles.merge. Check the documentation for more about data-sharing, see (for example):
