I'd like to get the windows taskbar height in normalised units. To this end I create a new figure, maximise it and get its position:

set(groot,'defaultFigureUnits','normalized') % set default units to normalised
figure('WindowState','maximized')            % create a maximised window
pos = get(gcf,'OuterPosition')              % get the outer position of the window
close all

Running this 4 commands one by one in the command window gives the correct answer:

pos =
   -0.0047    0.0403    1.0094    0.9681

While running them all together in the command window or as a part of the script gives:

pos =
  450.9953  299.9917  560.0094  420.0444

So matlab gives me the position in pixels instead of normalised units. I don't understand why, please help me.

The difference in solutions is due to the following reason

MATLAB calculates the original position faster than the figure to maximize.
So, you can include ‘pause’ to ensure that the maximized position is calculated. The period of pause needs to be more for older version systems.

f=figure('WindowState','maximized','Units','normalized'); % maximized screen and units are normalized
pause(1);  % delay the constructing recommended figure
position=f.Position; % to get the positions of figure
