Can I somehow use a variable from a pushbutton function to another pushbutton function

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".

Thank you. It worked for what I had to do
