数字图像处理中的经典问题之一——图像重构的matlab程序。(Digital image processing in one of the classic- the matlab image reconstruction process.)

tidal prediction source code

This program is written to control two inverters MM420 of siemens using PLC s7300

清华大学信号课程第二次实验，内容是基于傅立叶级数的信号分解以及双音频按键音合成(Tsinghua signal course the second experiment, the content is based on the Fourier series of two-tone signal decomposition and synthesis of key tone)

离散数据频谱分析，采样数据进行离散后，获取信号中的周期运动信息(matlab，FFT，frenquence chart)

这是胡不变矩的经典matlab程序，其实就是不变矩的验证，七阶矩.(This is the classic Hu invariant moments matlab program, in fact, the same moment the validation, seven-order moments.)

基于matlab的画出一个不完整的椭圆，结果完美。只要稍作修改可以出来任意要求范围的不完整椭圆。(Matlab to draw the ellipse )

系统辨识和控制方面的程序，适用于初学者，比较好(System identification and control procedures for beginners)

采用低通性质的平滑函数为高斯函数，根据他的一阶导数、二阶导数作为小波基函数进行突变点分析。 (The use of low-pass nature of the smoothing function for the Gaussian function, according to his first derivative, second derivative wavelet basis function as a point mutation analysis.)

说明：  实现匹配滤波仿真的两个程序，每个程序生成四个图，可以通过比较验证信号的时延不影响匹配滤波的输出信噪比，及不同信号信噪比与信号波形无关，只与信号能量有关(Matched filter to achieve the two simulation procedures, each of the programs to generate the four plans, you can verify by comparing the signal delay does not affect the matched filter output signal to noise ratio, and different signal-noise ratio and signal wave has nothing to do only with the signal energy relevant)
