he Principles and Practice of Iterative Alternating Projection Algorithm: Solution for Non-LTE Stellar Atmospheric Model With the Method of Linearized Separation

摘要

This paper is devoted to the application and practice of iterative alternating projection algorithm in the solution for non-LTE stellar atmospheric model with the method of linearized separation. By using the iterative alternating projection algorithm, a reduction of dimension and the removal of ill-conditioning may be realized. Its solution can converge to the least squares solution of the original solution, and this has been verified by practice. Therefore, the method of linearized separation can replace that of complete linearization in the solution for atmospheric models.
