abstract = {<p style="text-align: justify;">A variable-coefficient nonlocal diffusion model is discretized by an improved
fast collocation scheme. The resulting linear system has a symmetric positive definite
Toeplitz-like coefficient matrix. The preconditioned CG methods with Toeplitz and circulant preconditioners are used for solving the discretized linear system. Numerical
experiments demonstrate the effectiveness of the preconditioned CG methods.</p>},
