i have the following code that draws a scatter graph of values from 2 different matrices i would like to add x and y labels to the figure and automatically save it as .jpg without displaying the figure because it makes my laptop so slow.
figure(2); hold on
for i=1:numel(GRS_Fe_concentration)
plot(GRS_Fe_concentration(i),mag1(i),'*k');
end

" i would like to add x and y labels to the figure and automatically save it as .jpg without displaying the figure "
You can set the 'Visible' property of the figure to 'off' so that the figure never displays.
fh = figure(2,'Visible','off'); ; %the figure will not display
hold on
for i=1:numel(GRS_Fe_concentration)
plot(GRS_Fe_concentration(i),mag1(i),'*k');
end
xlabel('x axis')
ylabel('y axis')
figName = 'myFigure'; %specify the path, too; use fullfile()
saveas(fh,figName,'jpg');
Note that if you ever save the figure as a 'fig' instead of 'jpg', when you open the figure the visibility will still be set to off and you won't see it. You'll need to search for all figures and set their visibility to 'on'.
set(findall(0,'type','figure'),'Visible','on')
