Setting Paper Size in Matlab Figures

matlab_set_papersize

I repeatedly look for the code to specify paper size and attributes in matlab for figures. 
Here is how to do it : 


hFig = gcf; 

%# centimeters units
X = 42.0;                  %# A3 paper size
Y = 29.7;                  %# A3 paper size

% Or 
X = 8.0; Y = 12.0 ;  % custom size

xMargin = 1;               %# left/right margins from page borders
yMargin = 1;               %# bottom/top margins from page borders
xSize = X - 2*xMargin;     %# figure size on paper (widht & hieght)
ySize = Y - 2*yMargin;     %# figure size on paper (widht & hieght)

%# figure size printed on paper
set(hFig, 'PaperUnits','centimeters')
set(hFig, 'PaperSize',[X Y])
set(hFig, 'PaperPosition',[xMargin yMargin xSize ySize])
set(hFig, 'PaperOrientation','portrait')

% thanks for the folks on Matlab Forums & Stackoverflow for the codet.
