Hai,
I need to draw rays coming out of a lens after refraction. The rays should be drawn such that, after coming out of the lens, they seem to be going to infinity. How could I do this in matlab?

Because the monitor has finite limits, you cannot draw a line to infinity. Therefore arrows are used for such cases. See e.g. FEX: ArrowPlotter, FEX: marrow3, FEX: arrow-m, FEX: 3d-arrow, FEX: Arrow3
