Hello, I am working with the FOCUS Ultrasound code downloaded from the FOCUS website. I have this piece of code:

figure();

for it = 1:nt,

mesh(z*100, x*100, squeeze(p_tsd(:, :, :, it)))

title(['FNM TSD Example, t = ', sprintf('%0.3f',(it/fs) * 1e6), '\mu','s'])

zlabel('pressure (Pa)')

xlabel('z (cm)')

ylabel('x (cm)')

temp=axis();

temp(5)=-maxpressure;

temp(6)=maxpressure;

axis(temp);

drawnow

end

This provides me with a plot that is animated and shows me each piece getting plotted. I want to save this as a GIF for a presentation. However, when I save the figure, it only saves the final image, not the entire animation. How can I save the animation?
