convex hull function in matlab

Question

Is there any way to compute the convex hull of a finite set of points in Matlab and gives the half-space representation as its result?

I usually use a toolbox called MPT developed at ETHZ Zurich, but its results are not stable, and my problem requires a high precision with respect to high dimension of the points ( >= 4 ).

Answer 1

Not sure about the half-space representation. Can't you just calculate that yourself from the returned points?
