    Capacitance of Non-parallel plate capacitor

    Hi Sairajan, I assume that your two plates are conductors with dielectric material in between. If you can calculate the electric field everywhere, then the electric field near the plate (E is normal to the conducting plate) gives you the local charge density (since E = surface density of...

    'Distance' between MANY points ?

    Hi juliette sekx I am not sure what you are trying to do. But if you are dealing with a cloud of points and seeking some relative distance property among these points, then you may to do a Delaunay triangulation (see also convex hull). Very efficient algorithms exist that can handle many...
