Suppose I have:
figure
imshow(matrix)
hold on
scatter(x2,y2,size2,color2, 'filled')
axis square
axis off
colormap(c)
saveas(gcf,'image2.jpg','jpg')
A=imread('image2.jpg');
imshow(A);
QUESTION: how do I recover composite image A without having to save image2.jpg on the first place? there should be a shortcut!! Any help?

Why do you want it? It wouldn't be just your image, it would be that plus border padding, tick marks (if axis was "on"), title, etc. Of what use is this to your program if it were to be a variable (an image variable)?
That said, you can use getframe().

It won't be the size of the image of course, since you're grabbing extra stuff, and it also depends on how you sized the figure on the screen. What's your image size, what's your saved figure size, and what size are you expecting?
Have you tried export_fig()? See http://www.mathworks.com/matlabcentral/fileexchange/ for the most popular download.
