I have some rather complicated equations which Maple couldn' solve analytically. So I plotted the intersect (which worked) and now I wanted to extract the data from the plot to use it in Origin. I managed to get the data with the op comand but somehow I can't use writedata to create a txt file.

In addition does anyone now how to get the length of the output array from intersectplot?

Is there a better way to get what I want?
