Saving figures in matlab

Hi everyone, I have this function for saving my plotting my results, i want to know that how can i save these 3 figures to the hard-disk. Like everytime i run the simulation, these figures are saved and updated.

function plot_results()

%%definition of the global variable

global block_Pb theo_Pb Troughput total_delay arrival_rate

figure(1),
hold on;
plot(arrival_rate, block_Pb,'-r*', arrival_rate, theo_Pb,'-b*');
xlabel('Files arrival rate per user (Files/sec)');
ylabel('Blocking Probability (Pb)');
title('Comparison btw calculated Pb & Erlang Pb');
legend('Calculated Pb','ErlangB Pb');
hold off;

figure(2),
plot(arrival_rate, Troughput,'-b*');
xlabel('Files arrival rate per user (Files/sec)');
ylabel('Throughput (Mbps)');
title('Throughput verses files arrival rate');

figure(3),
plot(arrival_rate, total_delay,'-b*');
xlabel('Files arrival rate per user (Files/sec)');
ylabel('Total Transmission Delay (sec)');
title('Total transmission delay verses files arrival rate');

end

% Example

h=plot(sin(0:0.01:10))
saveas(h,'your_file.jpg')

[Azzi Abdelmalek]

You can also use hgsave and hgload functions

h=plot(sin(0:0.01:10))
hgsave(h,'fileame')

% to open your figure

hgload('filename')

if there a specific format that you're looking to save to? you can use the savefig() function to save it as a matlab fig file.

or if you want a jpg or something else you can use the saveas() function and do something like this.
