Suppose that I want to plot the convex hull of the following set of vectors: namely, \begin{equation} Co(X)=Co\{(1,0,1,1),(0,0,2,1),(0,0,1,2),(0,1,1,1),(1,1,1,0),(1,1,0,1),(1,2,0,0)\} \end{equation} Because the matrix given by the original set of vectors has rank $ 4$ , its convex hull does not lie in a three-dimensional space. However, the matrix given by my original vectors can be translatedRead more
