No UI on will survive to display 1.6E9 matrix elements directly. No human will be able to find something within this set. So the basic question is what you intend to visualize. You mentioned a sparse matrix. Maybe it is helpful to create an image with pixels that represent the values by their color. But this is still too much. Maybe you can combine 10x10 or more matrix elements to one pixel and provide a zoom function for the details. It is quite easy to find the nonzero elements this way. Marcel
