摘要
通过初等变换把任意一个m×n阶矩阵A化成简化阶梯形矩阵B。结合高等代数一类相关知识,充分挖掘简化阶梯形矩阵B的潜在含义,由B就可直接得到一系列重要结果,省去了大量繁杂的解题过程,深化了对这些结果相互关系的理解认识,使计算方法系统化。
A matrix A m×n is simplified to a trapezoidal matrix B by using elementary transformation. According to the knowledge of high order algebra, the potential meaning of the trapezoidal matrix B is exploited fully. A whole series of results can be worked out directly from B . Thus, many difficult processes of soloving mathematical problems can be cut off, and meanwhile, recognition of those results can be deepened, and comprechension of those results will systematizes the calculation methords.
