这是单自由度的非线性微分方程的求解程序（分段函数），可以画出动响应图和相图。(Nonlinear differential equation)

利用三角分解法这一算法，根据求得的电力系统节点导纳矩阵，求其相应的阻抗矩阵。本程序为IEEE经典算例009节点的程序，程序中附有解释性说明.稍加修改，可以适用于IEEE算例中任意节点。(Using the triangular decomposition algorithm, according to the obtained power system nodal admittance matrix, find the corresponding impedance matrix. The classic example is the program for the IEEE 009 node program, the program accompanied by an explanatory note. Slightly modified, can be applied to any node in the IEEE study.)
