Windows taskbar height in normalised units

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
