Local RBF-FD-Based Mesh-free Scheme for Singularly Perturbed Convection-Diffusion-Reaction Models with Variable Coefficients

Algorithm 1

Local RBF-FD scheme algorithm.

	Input kmin, kmax, increment
	k = 1;
	while (k < kmin or k > kmax). produce interpolation matrix say A; use [U, S,V] = svd(A); K = max(S)/min(S)
	if K < minK
	shape = shape − increment;
	elseif K > maxK
	shape = shape + increment;
	end
	end
