matlab中关于卡尔曼滤波的一些常用子函数及工具(One kinds of the Kalman filter can estimate the position of the ball.)

稀布阵列matlab波束形成程序，可画出9阵元稀疏阵列的阵列方向图和阵列布阵示意图，有详细的注释，适合初学者参考(thinned array beamforming)

提出一种基于Teager能量算子的小电流接地 系统的单相故障选线方法。通过EMD时空滤 波，在故障线路零序电流中提取暂态分量作 为特征量，以Teager能量算子法求得暂态分 量的瞬时频率、实际频率和幅值，进而得到 信号的能量均值，再以能量均值为故障判 据，从而检测出故障线路。经Matlab/Simulink 仿真验证，结果表明该方法的有效性，且算 法简便(Single-phase fault line selection method for the system. Time-space filtering through EMD)
