increase dimension plot window

i've recently changed my monitor with another bigger one; when i plot something the window is too small respect the screen so i'm searching for a command or option to increase the plot window;

i've searched info on internet but i found only to increase a singular plot with the strings

hFig = figure(1);
set(hFig,'units','normalized');
set(hFig, 'Position', [0.1 0.4 0.3 0.6]);

but it'not what i'm searching for; i want modify the default window size!!! someone can help me?

(i'm sorry for my english but i don't speak it very well!!!)

set(0,'DefaultFigureUnits', 'normalized', 'DefaultFigurePosition', [0.1 0.4 0.3 0.6])

Answer 2

[Azzi Abdelmalek]

hFig = figure(1);
set(gcf,'position',get(0,'ScreenSize'))

Note that this does not change the default size.

Also, watch out for the possibility that the figure Units is not pixels.
