I am trying to write a code which

Full screen the figure.
Plots the graph.
Change font size to 24.
Change line width to 2.
Turns grid on, and labels x, and y-axes.
Put a legend with font size 24.
Saves the file as eps, png, and fig with 600 dpi resolution.

figureFullScreen
loglog(x1, y1, x2, y2)
set(gca,'fontsize', 24)
set(findall(gca, 'Type', 'Line'),'LineWidth',2);
grid on, xlabel('\Delta x'), ylabel('Maximum Error')
legend({'Maximum Error in Conventional Scheme','Maximum Error in Proposed Scheme'}, 'FontSize', 28)
print(gcf, 'OneD_E1_a1_Convergence_Study_Max_Error','-depsc','-r600');
print(gcf, 'OneD_E1_a1_Convergence_Study_Max_Error','-dpng','-r600');
savefig('OneD_E1_a1_Convergence_Study_Max_Error.fig'),

For details of "figureFullScreen", please visit: https://www.mathworks.com/matlabcentral/fileexchange/31793-minimize-maximize-figure-window

Now I want to achieve

Save .fig file in 600 dpi.
expand axis to fill figure.

I need help with these 2 task.

Thank you.

See the 'Position' and 'OuterPosition' properties and 'Units'

I'm not sure you can enforce a specific dpi into the .fig file.

.fig files cannot be saved as a particular resolution. .fig files are copies of the graphics objects such as the line and legend objects as data structures. .fig files are not rendering of graphics, they are the data structures that you can reload to recreate the graphics objects.
