fcnFrostFilter performs noise filtering on an image based on an adaptive filter proposed by Frost. [1] V. S. Frost, et al., "A Model for Radar Images and Its Application to Adaptive Digital Filtering of Multiplicative Noise," IEEE Trans. Pattern Anal., Machine Intell., vol. 4, no. 2, pp. 157-166, Mar. 1982.

给出了线阵的指向性计算matlab代码，并绘制指向性指数(Gives the linear array of point calculations matlab code, and draw the point index)

逆变器使用的svpwm脉冲simulink仿真，脉冲和桥臂开关对应顺序已经注明。(Svpwm pulse inverter using simulink simulation, pulse, and bridge arm switches corresponding order has been noted.)

一个单相逆变器，控制环路采用的是MATLAB里面的PID模块，有电流环和电压环，PWM发波模块采用的是MATLAB里面的PWM模块，省去了spwm的脉宽调制，需要在matlab2013中使用，较低版本没法运行(A single-phase inverter control loop uses PID module of MATLAB, current and voltage loop, a PWM wave module adopts the PWM module of MATLAB, eliminating the SPWM pulse width modulation and need to use in matlab2013, lower version did not run)

说明：  主要是用于提取超声导波的时域特征，例如偏度参数、峰度系数、形状系数、离散系数等等(Time Domain Characteristics for Extracting Ultrasound Guided Waves)

使用matlab做的离散时间单位冲激响应(Discrete-time unit impulse response)

图像处理MATLAB源代码，这个是贝叶斯估计-bayes guess(Image Processing MATLAB source code, this is the Bayesian estimation-bayes guess)
