SOLVING A CLASS OF BOUNDARY VALUE PROBLEMS BY LSQR

ABSTRACT
Boundary value problems arising in fluid mechanics and thermal science can be transformed uniformly to a set of linear equations, whose coefficient matrix is circulant. This paper adopts a matrix iteration LSQR to solve the inverse of coefficient matrix. The solution process is elucidated step by step, and the numerical results reveal the effectiveness and feasibility of the presented method.
