No. A figure can never be a child of anything other than the root object.
Also, an axes can never be the child of another axes.
It is possible to place images within axes, if that is what you are looking for. Just set() the image Parent property to be the target axes. You might also want to set the image XData and YData properties to move the image around within the axes.

Yes, a generated image of a figure would be sufficient for what I need. How do I generate an image of a figure?

To save a figure as an image to an image file, try the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions. which recommends using export_fig() - the most downloaded File Exchange file.

Sorry - I guess I misinterpreted when you said "generate an image." Like Walter said, you can use getframe to get the contents of the figure into a variable in your program, but what are you're going to do with it? What's the point, when you already have the data that went into making up the figure? Why obtain that image if you're not planning on saving it out to disk?

Thanks for your guys' support. I'll be using the getframe method.
