Abstract:
An algorithm for multiple solution of systems of linear algebraic equations by preconditioned BiCGStab method is proposed. When the number of iterations for solving a current system becomes too large, the precontioner is recomputed. Results of numerical experiments on computing the capacitance matrices of a microstrip line in a wide range of its sizes, demonstrating the possibility of a considerable reduction of the total solution time, are presented.
Key words and phrases:computational costs, systems of linear algebraic equations, block LU decomposition, preconditioning, multiple solution, capacitance matrix, microstrip lines.
