本文介绍了矩形矩阵的LU分解的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
方法lu
对于平方矩阵很好用.但是,我看不到为什么有square
限制.如何在矩形矩阵上执行LU分解?
Method lu
of package Matrix
works fine for square matrices. However, I can't see why there is that square
restriction. How can I perform LU decomposition on a rectangular matrix?
推荐答案
您可以将其嵌入到身份矩阵中:
You can embed it into a identity matrix:
[ a11 a12 a13 ]
[ a21 a22 a23 ]
[ 0 0 1 ]
LU分解仅适用于平方矩阵.您可能需要查看维基百科以获得刷新.
LU decomposition is for square matrices only. You may want to check Wikipedia for a refreshing.
