Abstract:

The biconjugate gradient stabilized (BCGSTAB) method is a fast and smoothly converging variant of biconjugate gradient (BiCG) method. In this paper, we generalize BCGSTAB method to solve the Stein tensor equation. We raise the algorithm of tensor format and specific proof process of existence of a solution. And we present the convergence theorem of this algorithm. Numerical experiments demonstrate this algorithm is effective and feasible for solving the Stein tensor equation.
