摘要
对非零矩阵A,存在可逆矩阵P,使PA为阶梯形或最简形矩阵,对于P的唯一性问题,现行教材没有介绍,这给学习者带来一定的困惑,讨论了可逆矩阵P的唯一性,同时介绍行阶梯形、最简形矩的有关应用.解决了P的唯一性问题,在线性代数学习中具有一定的应用价值.
For the non-zero matrix A,there is an invertible matrix P,Charging PA into the stepped form or the simplest form.The uniqueness of P is not introduced in the current textbook,which may bring some confusion to learners.In this paper we will discuss the uniqueness of reversible matrix P,and also introduce the application of row echelon form and the simplest form moment.The study solves the problem that the uniqueness of P,which has certain application significance in linear algebra learning.
