[Scilab-users] Filled polygons from polylines

[Antoine Monmayrant]

Hello all,

I think I answered this question before on this mailing list...

Ah, yes I did:

http://mailinglists.scilab.org/Reg-Area-Between-two-curves-td3393261.html#a4026721

Get the source for "[h,epoly,ey1,ey2]=BetweenCurves(x,y1,y2,varargin)" 
in the thread.

Hope it helps,

Antoine
