改进boll谱减法，语音增强效果有提高。与MMSE算法不相上下(Improved the boll spectral subtraction speech enhancement effect has been improved. Comparable with the MMSE algorithm)

计算指定位置的固体潮,并绘制固体潮的时变曲线(calculate gravity tides)

基于云模型的PID控制算法，可以大大提高控制效率(PID control algorithm based on cloud model, can greatly improve control efficiency)

信号处理中短时傅里叶变换（STFT）的实现，可用于实时系统，实时语音处理或者分段的FFT计算，亲测可用，拿走不谢！(The implementation of short time Fourier transform (STFT) in signal processing can be used for real-time system, real-time speech processing or segmented FFT calculation!)

matpowe3.1b2 Open source software, no modified version downloaded from the official website, different matpower may not apply with each other program

filter design code which describe filter design of low pass filter using window function

用于二维平面的闭合曲线三次插值，通过给定的几个坐标点，完成闭合曲线的三次插值函数(Closed curve cubic interpolation for two-dimensional plane, through a given number of coordinate points, complete the closed curve cubic interpolation function)

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

偏微分方程的matlab程序，可作为数值分析等的学习工具。(Partial differential equations matlab program, can be used as numerical analysis , and other learning tools.)
