摘要
通过系统研究乘积矩阵ATA的性质,然后运用这些性质提出了求规范正交基的一种新方法——消法初等列变换方法,还给出了编写正定矩阵例题的技巧以及判定一组向量线性相关的方法。
The paper systemically studies the character of the matrix ATA and applies these characters to put forward a kind of new method for solving orthonormal basis, i.e. primary row transformation by eliminating method. The paper also provides the skill of editing positive definite matrix and the method of judging vectors' linear correlation.
