基于神经网络的人脸识别，主要识别人脸的面对的方向，开发环境matlab(Face recognition based on neural networks, mainly face to face identification of the direction, development environment matlab)

This code uses the output from make_zeta.c file i.e. it uses the displacement of any particular isotherm and outputs the time series of the displacement to zetafile??degC.dat file. Furthermore, this code filters the isotherm displacements, plots the filtered and raw signals at certain specified locations and then creates maps of the isotherm displacement time series

一台三相感应电动机，参数分别为：230V，60Hz，12kW，4极绕线式转子， 利用Matlab软件绘制电机的机械转矩Tmech作以r/min为单位的转子转速的函数时的变化曲线(A three-phase induction motor, the parameters are: 230V, 60Hz, 12kW, 4 pole wound rotor, Drawn using Matlab software for the motor to the mechanical torque Tmech r/min as a function of the unit when the rotor speed curve )

Wigner-Ville 分布(简称 WVD)是典型的二次型变换，它定义为信号瞬时相关函数的傅立 叶变换。 由于在计算中不加窗操作，它避免了时域分辨率和频域分辨率之间的相互牵制。 已证明，对于单分量线性调频信号，WVD 的时频表示能量集中性最优。但也正因为不涉 及窗函数，在分析多分量信号时 WVD 会受到交叉项的干扰。(The Wigner-Ville distribution (WVD) is a typical quadratic transformation, which is defined as the Fourier of the instantaneous correlation function of a signal. Ye Bianhuan. Because of no window operation in the calculation, it avoids the mutual restraint between time domain resolution and frequency domain resolution. It has been proved that for the single component LFM signal, the WVD time frequency representation has the best energy concentration. But it is also because it does not involve. And window functions, when WVD is used to analyze multi-component signals, it will be interfered by cross terms.)
