%% Set exact figure size.

x1 = -2.5:0.5:2.5; y1 = sin(x1)

fh3=figure(3); plot(x1,y1,'--rs','LineWidth',2,...
'MarkerEdgeColor','k',...
'MarkerFaceColor','g',...
'MarkerSize',10)

% save your plot as png file
print(gcf,'./default_figure_size.png','-dpng')
% result will be defaulted to 1200x900 pixels, since the default size is 8x6 inches
% with default dpi 150 (dot per inches)
% What is worse, the size of the label and marker is changed.


% specify location and zise of the figure on your screen.
% no effect on out put png file.
set(gcf,'position',[100 10 800 400]); % gcf: get current figure (result in a handle)
set(fh3,'position',[100 10 800 400]);

% to prevent the change of dimensions of the figure printed out as png, use:
set(gcf,'PaperPosition',[0 0 800/100 400/100]);
print(gcf,'-dpng','-r100', ['./Size_800x400.png']);
% -r100 100 dpi, dots per inch


% Again, to save figure almost exactly what it looks on your screen, use:
figure_size = get(gcf,'position')
set(gcf,'PaperPosition',figure_size/100);
print(gcf,'-dpng','-r100', ['./same_as_on_screen.png']);
