How to take a given plot and write it as an image

I have created the plot of an ellipse that is shaded in successfully. now i would like to take that plot and write it to an image, say "pic.jpg"

Here is the code so far:

function out = drawEllipse(x1,y1,x2,y2,h,w,d)

P = zeros(800,800);
P(1:800,1:800) = uint8(255);

[h,w] = size(P);
imagesc(P),colormap white,hold on;

c = 1/2*sqrt((x2-x1)^2+(y2-y1)^2);

a = d/2;

b = sqrt(a^2-c^2);

t = linspace(0,2*pi,1000);

x = (x1+x2)/2 +(x2-x1)/(2*c)*a*cos(t) - (y2-y1)/(2*c)*b*sin(t);

y = (y1+y2)/2 +(y2-y1)/(2*c)*a*cos(t) +(x2-x1)/(2*c)*b*sin(t);

plot(x,y)

fill(x,y,'black');

axis equal

what i actually want to do is to add another input to the function, being "pic.jpg" and actually write this plot to the image file in the function.

any thoughts? thanks for all your help! you all have been very helpful thus far!
