当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

基于matlab利用小波分析对二维信号进行去噪处理(Based on the Matlab wavelet analysis of two-dimensional signal denoising)

Zernike calcilations code

This is an implementation of Particle Swarm Optimization algorithm using the same syntax as the Genetic Algorithm Toolbox, with some additional options specific to PSO. Allows code-reusability when trying different population-based optimization algorithms. Certain GA-specific parameters such as cross-over and mutation functions will not be applicable to the PSO algorithm. Demo function included, with a small library of test functions. Requires Optimization Toolbox.
