图像受到裁剪攻击时的一些算法 只要输入图像和想要裁剪的位置 就可以得到想要的结果(Images by cutting attack some algorithm as long as the input image and want to cut position can be the desired results)

四节龙格库塔程序，这是一个很高的程序，快来下载吧，齐纳的朋友么(this is a good for everything)

去斜率（strech）参考信号与回波信号混频后得到中频输出信号S(t)=Aexp(j*2*pi*f0*t+phase) 其中f0与回波延时的关系为： f0=k*delay_t K为线性调频斜率，delay_t为回波延时 将s(t)采样，FFT变换即可得到目标距离与频谱的关系。 Strech 信号测距 输入混频后的中频信号（图一），经采样及FFT变换得到频谱（图二） 再根据频谱与距离的关系式R=Tcf/2B显示出距离(图三) (Go slope (strech) obtained after the reference signal and the echo signal mixer IF output signal S (t) = Aexp (j* 2* pi* f0* t+phase) f0 and echo delay relationship: f0 = k* delay_t K chirp slope, delay_t the echo delay sampling s (t), the FFT transform to the target distance spectrum of relations. Strech signal ranging input mixer IF signal (Figure 1), sampling and FFT transform spectrum (Figure 2) according the the spectrum distance relationship R = Tcf/2B shows the distance (Figure 3))

Matlab 降噪程序，使用LMS算法去除噪声，在一段添加噪音的音频文件中滤除噪声！(Matlab Noise reduction LMS)

用matlab对图象实施预测编码和解码，并将原图象与解码图象进行方差计算。(Using matlab implementation of image predictive coding and decoding, and the original image and the decoded image variance calculations.)

说明：  文件中是 MATLAB的模糊 PID控制程序。主要是用一个模糊控制表来进行查询(Paper is MATLAB Fuzzy PID control procedures. Is a fuzzy control query table)
