本程序为直接LU分解法及其MATLAB程序，用于求解高斯方程组(This procedure for direct LU decomposition method and the MATLAB program for solving equations Gauss)

说明：   M-file for Project 1 on line parameters and circuit models in Chapter 3 m1.m determines the RLC parameters of the line from its physical description and then computes the ABCD matrix and the circuit parameters of the series RL, nominal pi and equivalent pi model of the line. It computes and plot the receiving-end real and reactive power circle diagram of the line assuming that the voltage magnitude at the sending- and receiving-end are kept constant.
