基于MATLAB实现磁链计算，程序调试成功，可直接使用(Flux calculation based on MATLAB implementation, debugging success can be directly used)

交织器的程序，可用在turbo 码生成中的交织算法(the program of interleaver, can be used on the interleaver arithmetric)

matlab实现kalman滤波，并标注(kalman filter)

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))

数字图像频域滤波处理，分别进行二阶巴特沃斯(Butterworth)高通、低通滤波器。(Digital image processing frequency domain filtering, respectively second-order Butterworth (Butterworth) high pass, low pass filter.)

虚拟示波器,硬件基于NI系列AD采集卡,软件基于Matlab7.9(virtual oscilloscope hardware config: National Instrument A/D card software config: Matlab 2009以上版本)

利用一个彩色图片，利用matlab编程编成一个有可动倒影的图像(The movable reflection )

没有用工具箱的DCT变换，采用不同压缩率，能够加深对DCT变换的了解。(Do not use toolbox of DCT, using different compression ratios, to deepen understanding of the DCT transform.)

说明：  一个空时编码方面的simulink，好东西大家分享！(a space-time coding of Simulink, to share the good things!)

matlab插值法、牛顿法、高斯消元法，主要用于matlab的程序调用(mainly be usd with matlab )
