Iterative methods for X-AXE=C

[摘要] Alternating direction implicit iterative methods for the solution of matrix equations of the form X - AXB = C are described. A convergence analysis based on potential theory shows that iterating in one direction more than the other can give faster convergence than strict alternation of directions. Computed examples illustrate an application to the restoration of images degraded by noise.
