Hi I have been using lsline to produce a linear line of bext fit for two datasets. I was wondering if there was a similar command that produced the line of best fit and provided an equation (in the form y=mx+c) for said line. Many Thanks ...
Linear Equation(线性方程)Why Matrix Form?更方便计算,也更简洁如何解线性方程组?常用的两种方法:1. Successive elimination (through factorization) 逐次消除(通过因子分解)又可以分为 Gaussian Elimination 和 LU Factorizationa Gaussian Elimination MATLAB 中使用 Gaussian Elimination – rref()函数...
