M=courantFunctions(V,F)
This method returns a matrix with as many rows as facets and as many columns as vertices. Column $i$ of the matrix is the Courant function corresponding to vertex $V_i$. This is the piecewise linear function which takes the value $1$ at the vertex $V_i$ and $0$ at all other vertices.



If the option Homogenize=>false is given, the Courant function corresponding to a cone vertex (if there is one) will be discarded.


The Courant functions are used to construct the Stanley Reisner ring of a simplicial complex. See stanleyReisner.
The object courantFunctions is a method function with options.
