If you have something that you want to permanently save to an image file on disk, see 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.
If you have something temporary and the user will need to change it in the second running of your program, then you're going to have to save all the various parameters that created the shapes in the first place, such as their vertex coordinates, line widths, colors, etc., to a mat file and then recall them and reconstruct your figure.
