[Scilab-users] Filled polygons from polylines

[CRETE Denis]

Hello, I did not look carefully at the function "BetweenCurves", but it requires y1 and y2 to share the same x data. Isn't it a limitation ? Would it be useful to extend it to the case where x1 and x2 are not identical ?
Best regards
Denis

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
