numpy错误:奇异矩阵 [英] Numpy error: Singular matrix

问题描述

错误Numpy error: Matrix is singular的具体含义是什么(使用linalg.solve函数时)?我查看过Google，但是找不到任何可以清楚地表明发生此错误的信息.

What does the error Numpy error: Matrix is singular mean specifically (when using the linalg.solve function)? I have looked on Google but couldn't find anything that made it clear when this error occurs.

推荐答案

奇异矩阵是不可逆的.这意味着您要求解的方程组没有唯一的解； linalg.solve无法处理此问题.

A singular matrix is one that is not invertible. This means that the system of equations you are trying to solve does not have a unique solution; linalg.solve can't handle this.

您可能会发现linalg.lstsq提供了一个可用的解决方案.

You may find that linalg.lstsq provides a usable solution.
