See the FAQ: How do I create a circle? You can take the 4th example and make it do an ellipse by giving x and y different sized radii. Good luck.

C = bsxfun(@(x,y)hypot(x-50,y-50)<25,1:100,(1:100).'); %A circle
tform = [1 0 0;0.6 1 0;0 0 1]; %a transformation
tform = maketform('affine',tform); %create tform structure
C2 = imtransform(C,tform,'Size',size(C)); %transform
imshow(C2) %show

Whom are you talking to? You should put your follow up question as a comment to someone. You put it as an Answer to your own question, so basically you're asking yourself. To make something change gradually, you must change the input parameters gradually.
