m = 800;
n = 600;
im = zeros(800, 600);
      y0 = 12;
      x0 = 12;
      a = randi(round(m/3));
      b = randi(round(n/3));
      c = max(a, b);
      c1=0.1;
      theta = 2*pi*rand(1);
      color = 249;
      color2 = 120;
      disp(i)
      im = ellipseMatrix(y0, x0, a, b, theta, im, color, color2, randi(2));
colormap(gray(256));
image(im)

What is your question? What is the problem? What is "ellipseMatrix"? Do you mean the FileExchange submission http://www.mathworks.com/matlabcentral/fileexchange/17499-ellipsematrix-y0--x0--a--b--theta--im--c1--c2--pinterp-?

yes. i used FileExchange submission. I got the desired output. thanks.

    m = 800;
    n = 600;
    im = zeros(m, n);
    y0=400;
    x0=300;
    a=286;
    b=60;
     theta = pi/2;
     color = 169;
     color2 = round(color/3);
     im= ellipseMatrix(y0, x0, a, b, theta, im, color, color2, randi(2));
    colormap(gray(256));
    image(im);
