基于神经网络的人脸识别的一种算法，给出了计算识别率的方法(Neural network-based face recognition algorithm, gives the recognition rate calculation method)

说明：  一个统一的求无约束优化极值函数，方法名由参数传入例如：fmins(无约束方法，一维搜索方法，目标函数，初始点，精度) (A uniform evaluation of unconstrained optimization extremal functions, methods, for example, by an argument: fmins (unconstrained one-dimensional search method, the objective function, the initial point accuracy))

arima时间序列模型，对一个序列进行也测(arima time series models, also measured on a sequence)

something about phisics

说明：  《信号与系统》计算机练习－利用matlab 西安交通大学出版社 实验二("Signals and systems" computer exercises-using Matlab Xi'an Jiaotong University Press Experiment 2)

说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)

说明：  交流调速系统仿真模型：SPWM变频调速系统模型-5；方波永磁电动机调速系统-8；交-交变频调速系统模型-3；交流调压调速系统模型-1；交-直-交变频调速模型-4(Simulation model of AC speed regulation system: SPWM Frequency conversion speed regulation system model-5; square wave permanent magnet motor speed regulation system-8; AC-AC frequency conversion speed regulation system model-3; AC voltage regulation speed regulation system model-1; AC-DC-AC frequency conversion speed regulation model-4)
