1. Choose positive integers m1 and m2 and a constant 0>1 and set hi =0 for i =1, 2, . . . , n.2. Assemble a set of points P in three steps:(a) Create a [m1]d uniform grid of points over C and discard those falling outside.(b) Add m2 random, uniformly distributed points in C.(c) Add the nodes {xi }ni=1.3. For each p ∈P,(a) Find the d+1 nodes {xi∗ }d+1i∗=1 in {xi }ni=1 that are closest to p, and compute their Euclideandistance di∗ = p − xi∗ .(b) If hi∗4. Set rmaxi=hi for i =1, 2, . . . , n.For the 2D applet, m1 =100, m2 =10 000, 0 =1.01, and the constant is chosen by the user viaa slider. This procedure is necessary to ensure that every point in C is covered by at least d + 1nodal weight function supports, so that the matrix A(x), defined in Equation (10b), has full rank.
