// Generate matrices M that allow to obtain a fair placement of high-order
// interior nodes when only boundary nodes are given.
// If x^b are x coordinate of boundary nodes, then x coordinate of interior
// nodes are given by M*x^b.
// The placement is obtained by analogy with linear transfinite interpolation.
 
// TODO Amaury: Create sparseMatrix?
