Just imagine you plot several dots, circles, lines in a figure. Afterwards another m file should use this plot as an input to do e.g. thresholding. I'm aware of the print command but I don't want the plot to be stored as file. I would prefer to store it in a matrix (x_dim,y_dim,3). Any ideas?

You should check out the functions
getframeandframe2imto convert a figure or axes object to an image matrix.How about save to an image? You can use
getframeto get a frame object F, where F.cdata contains the RGB values. Remember to use'border', 'tight'option to avoid capturing the borders.
