We analyze a least-squares asymmetric radial basis function collocation method for solving the modified Helmholtz *** the theoretical part,we proved the convergence of the proposed method providing that the collocation points are sufficiently *** numerical verification,direct solver and a subspace selection process for the trial space(the so-called adaptive greedy algorithm)is employed,respectively,for small and large scale problems.
