代码里有很完整的注释和解释，包含了阵列信号处理的常见算法，包括调制，解调，信噪比计算，快速扩展随机生成树算法，包含特征值与特征向量的提取、训练样本以及最后的识别。(Code, there are very complete notes and explanations Contains a common array signal processing algorithm, Includes the modulation, demodulation, signal to noise ratio calculation, Rapid expansion of random spanning tree algorithm, Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition.)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)
