Figure of screen size

How can I get the figure window of exactly the same size as that of my screen? Also how can I draw axis on this full figure window? Please help! Any help will be highly appreciated!

If you are in R2014b you can get screensize programatically as:
screensize = get( groot, 'Screensize' );
In previous versions if I remember correctly it would be:
screensize = get( 0, 'Screensize' );
may also help for advise on maximising a figure programatically.
I've never used Simulink so I don't know what is valid there I'm afraid.

One solution to bypass the problem of being connected to different screens that might have different resolution (screen sizes), is to use the following:
figure('units','normalized','outerposition',[0 0 1 1])
This way the outer position of the figure window is normalized to whatever screen is used. Found this solution from an older post here: https://www.mathworks.com/matlabcentral/answers/102219-how-do-i-make-a-figure-full-screen-programmatically-in-matlab

If your screen has for example the resolution 1920x1080:
fig1 = figure;
pos_fig1 = [0 0 1920 1080];
set(fig1,'Position',pos_fig1)
In the pos_fig1 vector the first and the second values are coordinates x and y of the lower left corner, the other two numbers are the length and the depth

ad the programs stops and shows
Undefined operator '+' for input arguments of type 'matlab.ui.Figure'.
Error in nnvalid (line 249) figure(si+ii)
Error in ModelScaled (line 115) [Yhat,NSSE]=nnvalid(Model,NetDef,NN,w1,w2,Yv(:,Nr)',Uv');
but on earlier version i.e. R2013 it works proprly . What to do ?

1. This isn't related to this original question, so you should have created a new post for it.
2. As noted in the documentation for the major graphics changes introduced in release R2014b, "Graphics Handles Are Now Objects, Not Doubles". Don't try to do arithmetic on graphics objects. If you must try to create figures with sequential numbers, that will still work, but adding a figure object and a number won't.

If you're using release R2018a or later, use the WindowState property of figure objects. See the description of this property on the Figure Properties page for information about the allowed values.
