matlab 绘制偏微分方程的函数 对于绘制偏微分方程的函数和边界曲线非常有参考性(matlab draw a function of partial differential equations for the mapping function of partial differential equations and the boundary curve of a very good reference of)

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.
