Can I somehow use a variable from a pushbutton function to another pushbutton function
显示 更早的评论
Xp_1=0;
Yp_1=0;
Xp_4=0;
Yp_4=Y_val;
Xp_3=X_val;
Yp_3=Y_val;
Xp_2=X_val;
Yp_2=0;
Xp=[Xp_1,Xp_2,Xp_3,Xp_4];
Yp=[Yp_1,Yp_2,Yp_3,Yp_4];
hold(app.UIAxes_10,"on");
plot(app.UIAxes_10,Xp,Yp);
[xi,yi]=getpts(app.UIAxes_10);
p = [xi yi];
I want to use [xi,yi] in another pushbutton function

Yes you can but you will have to store the data. A decent choice is the UserData field of the gui figure, root object or guidata.
At the time you create the gui figure you could place a tag:
hf = uifigure('HandleVisibility','on',...
'Name','Flight Data Analysis', ...
'Toolbar','none','MenuBar','none','Resize','off',...
'Color',[1 1 1],...
'Tag','MainFig');
and then within a button callback function find the object and assign or read data from the UserData field:
mf = findobj('Tag','MainFig');
data = mf.UserData;
Other places to store data are "guidata" or using the UserData field of the root object with "groot".
