进行Iris数据分类实验，使用matlab构建bp神经网络(Iris data classification experiments, using matlab to build the bp neural network)

这个源码是最小二乘法在Matlab上应用的一个例子，可供大家参考(This source is the least squares method in the Matlab application of an example for your reference)

9节点前推回代法潮流计算，基本潮流！源程序(9 nodes forward and backward substitution method flow calculation, the basic trend! Source)

测量6205深沟球轴承的故障振动加速度信号, 对信号进行时频分析, 利用经验模态分解方法将振动信号分解成不同特征时间尺度的固有模态函数,对每个固有模态函数进行Hilbert 变换得到Hilbert 谱,通过谱分析识别轴承的故障部位和类型, 证实Hilbert 谱的有效性(Measuring 6205 deep groove ball bearing fault vibration acceleration signal, the signal frequency analysis, empirical mode decomposition method to decompose the vibration signal into different characteristic time scales of intrinsic mode functions, the Hilbert transform of each intrinsic mode functions Hilbert spectrum, spectral analysis to identify the location and type of bearing failure, confirmed the effectiveness of the Hilbert spectrum)
