All,

Has anyone done any coding with the marith.mp package of Metapost? Any code that you can share?

My specific task is to draw the polynomial x^3-7*x^2+7*x+15 on the domain [-50,50].

I have only ever used sarith (once, because it was part of a technical drawing and I didn't want to switch to some other engine for just one image), but normally I do function plots to GNUplot, where this is much less hairy to do. So sorry, no. Taco
