- What I am doing is reading in an 8-bit image and would like to

- What I am hoping is that there is some way in Matlab to turn
- off the redraw/refresh??

- In Matlab 4, you can do this by specifiying a plot as a graphics
- object then using the 'set' command to change the data in the plot
- without redrawing the axis. Look at ODE23P for further clues.
