粒子滤波讲解，是PPT讲解，讲的挺好的，拿来分享(The particle filter explain, PPT to explain, speak very good for them and share)

模糊神经网络逼近二维非线性函数，我自己编译的程序，希望大家喜欢(Fuzzy neural network approach to two-dimensional nonlinear function)

数字信号处理和滤波器设计，希望对大家有帮助。(Digital signal processing and filter design, in the hope that everyone has to help.)

easy code taking picture from web cam and showing the countours - use the logarithm filter

用split-step方法求解非线性薛定谔(NLS)方程的例子(This code solves the NLS equation with the split-step method)

用MATLAB实现的基4FFT算法的程序，输入一个长度为16的序列，得到DFT的频谱(Implemented with the MATLAB-based algorithm 4FFT program, enter a sequence of length 16 obtained DFT spectrum)

说明：  matlab在机械设计的应用，文件结合实例的哦(matlab in the mechanical design of the application, file with examples)

说明：  分变模态分解（Variational Mode Decomposition，VMD）是一种具有坚实数学基础的分解算法，能够通过建立约束变分模型表达式，将信号以非递归的方式自适应地分解为若干本征模态分量(Variational Mode Decomposition is a decomposition algorithm with solid mathematical foundation. It can adaptively decompose signals into eigenmodes in a non-recursive manner by establishing constrained variational model expressions.)
