摘要
本文给出了一类多个变量的周期性约束条件处理方法。在保持原系数矩阵对称正定特性不变的情况下，该方法减小了求解规模。
This paper gives a method for removing multivariate periodical constraint coditions, while the number of variables can be reduced, and symmetry and positive definite properties are maintained. By this way, the running time and stored space can be reduced. It is proved that the method is exremely convenient and effect in practice.
