We turned the singular boundary value problems to nonsingular problems, and presented a numerical method for them. 通过变换将奇异边值问题转化为非奇异边值问题,提供了求解这类奇异边值问题部分数值解的数值求解方法。
We call a matrix the generalized cyclic matrix if it can be written the product of a nonsingular diagonal matrix and a cyclic matrix. 摘要可表为非奇异对角矩阵和循环矩阵乘积的矩阵,我们称其为广义循环矩阵。
