实对称矩阵的对角化

Diagonalization of Real Symmetric Matric

关于实对称矩阵的对角化问题在各种线性代数教材中都有介绍,但证明过程都省略了,只要求学生根据定理的结论会求那个正交矩阵就可以了。在数学专业的高等代数中用的证明方法理工科的学生又看不懂,本文主要用一种理工科学生能看懂的方法进行了证明。

About real symmetric matrix diagonalization in various linear algebra textbooks are introduced,but the proof is omitted,and only require students to conclusions based on the theorem that the orthogonal matrix will seek it.Advanced Algebra in mathematics professional methods used in science and engineering students to prove that they do not understand,this paper in a science and engineering students can understand the method is proved.
