摘要
运用初等变换的正确步骤可以减少计算量,现行用初等变换求向量组的一个极大无关组的两种方法,各有所长,文[5]的批评是不全面的.
The operation can be reduced by the exactly step of elementary transformation. Today, there are two kinds of methods which are used to find maximal linearly independent subses. Every method has its merrt. The discussion in [5] is not comprehensive.
