超声波扫查中，用线性阵元实现实现线性扫查，扫查体为自定义囊，对接收的回波数据进行hilber变换，获得其包络信息，在对包络信息进行对数压缩，用8为2进制数显示()

说明：  PSK信号的同步技术和方法，供信号解调用(PSK signal synchronization techniques and methods for the output signal called)

constrained linear least square implementation

fmincon finds a constrained minimum of a function of several variables. fmincon attempts to solve problems of the form: min F(X) subject to: A*X <= B, Aeq*X = Beq (linear constraints) X C(X) <= 0, Ceq(X) = 0 (nonlinear constraints) LB <= X <= UB (bounds)

说明：  MATLAB图像处理工具箱提供了灰度调整函数imadjust()，可以将图像的灰度值调整到一个指定的范围(MATLAB image processing toolbox provides a grayscale adjusting function imadjust (), you can adjust the gray scale image to a specified range)

AR自回归模型，主要介绍时间序列分析中重要的一个模型。(AR autoregression model, time series analysis introduces an important model.)

多重比较LSD法实现方差分析的matlab代码，调用格式为输入A矩阵，每一列是一个因素水平，当重复数不相等时，缺失数据用nan补齐。输出参数为各均值的比较表。(Multiple variance analysis method to achieve more LSD matlab code, call format for the input A matrix, each column is a factor level, when the number of repetitions is not equal, nan filled with missing data. Output parameters for the mean comparison table.)
