How do you make a MATLAB's `uifigure` appear in the center of the screen?

Question

One can easily use the Position property to place a uifigure in the specified location of the screen. E.g., fig = uifigure('Position',[1,1,300,300]);. Is there any way to place it immediately on the center of screen.

There is a movegui command which is helpful for this task. However, it does this work in two steps (first, displays the figure, then moves it). This results in a not smooth experience for the user.

Answer 1

We need to get the screen size to determine the center. The code below will create a figure at the center of the screen.

% width and height of the figure
width = 300;
height = 300;

% screen size
sz = get( 0, 'ScreenSize');

% center position
x = mean( sz( [1, 3]));
y = mean( sz( [2, 4]));

fig = uifigure( 'Position', [x - width/2, y - height/2, width, height])

Answer 2

Use

movegui(app.UIFigure,'center')
