MATLAB

说明：  用混合同余法生成两组伪随机数，利用投针试验求圆周率。软件：matlab。(Two groups of pseudo-random numbers are generated by the method of mixed congruence, and the circularity is calculated by the test of inserting needle. Software: MATLAB.)

本程序是用节点导纳矩阵计算三相短路电流 输入数据--形成节点阻抗矩阵--选择故障点---计算短路电流----计算个节点电压---计算指定支路的电流(this procedure is used node admittance matrix calculation of three-phase short-circuit current input data-- forming node impedance matrix-- election Optional fault--- calculation of short-circuit current-voltage computing nodes designated calculated slip road--- Electricity)

说明：  本程序计算的太阳角有地面点对应的太阳天顶角和太阳方位角，太阳高度角与太阳天顶角 互余，所以太阳高度角也可以通过90 度-太阳天顶角计算得到(The solar angle is calculated by the solar zenith angle and the sun azimuth angle corresponding to the earth's surface point. The sun height angle and the sun zenith angle are complementary, so the sun height angle can also be calculated by the 90 degree sun zenith angle.)
