Fic Question

To all you math savvy people out there. This is for my undermistletoe fic.

So I know that Matlab can make graphs when you input functions. I need the name of a program that works the other way. Something linux compatible that can approximate equations for graphs plotted from lab data.

Hmmmm.

I have realized that I hate being in the car when my cousin drives. She is a discourteous driver. ( small rant to follow )

So, I'm amused to discover that my undermistletoe fic and "Grace Under Pressure" are inexplicably ( spoilers )
