说明：  介绍MATLAB使用的相关知识和技巧，对入门者比较有用。(MATLAB introduce the use of relevant knowledge and skills useful for beginners comparison.)

说明：  matlab下利用相位相关对待匹配图像完成配准(matlab treated under the matching images using phase correlation to complete registration)

该编程为矩阵与数据分析课的编程作业程序，里面包括matlab的三次样条曲线程序，有Jacobi迭代法和Gauss-Seidel迭代法等(The programming and data analysis for the matrix class programming operations program, which includes the cubic spline curve matlab procedures, Jacobi and Gauss-Seidel iterative method iterative method)

The PSNR is most commonly used as a measure of quality of reconstruction of lossy compression codecs (e.g., for image compression). The signal in this case is the original data, and the noise is the error introduced by compression

The TSP problem ant colony algorithm MATLAB source code

Inverse of DFT in cpp language....

单次脉冲产生,或者周期脉冲产生.周期时间或脉冲宽度可以调节.(Single pulse, or cycle pulse. Cycle time or pulse width can be adjusted.)

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)

PCA算法的matlab程序。本代码是对一维信号进行PCA降维处理的matlab函数。(PCA algorithm matlab program. This code is a one-dimensional signal processing PCA dimensionality reduction matlab function.)
