该程序是对声音信号的滤波，采用的是小拨变换滤波，最后画出波形，希望对大家有用(The program is a voice signal filtering, using a small dial transform filtering, the final draw waveform, in the hope that useful)

matlab程序的一些算法，需要的同学可以直接引用(Matlab procedures some algorithm, the needy students can directly apply)

粒子滤波算法实现的matlab源代码，并配有相应的说明文档，对于原理到代码的实现过程学习具有很好的作用。(Particle filter algorithm matlab source code, and with the corresponding documentation, for the principle to the code to achieve the learning process has very good effect. )

一种基于最大域值平方法的目标识别算法程序.rar(A domain based on the maximum value of level of target recognition algorithm approach procedures. Rar)

电磁场和电磁波中相速度和群速度是个难点，本程序形象描述二者关系(Analog of the group velocity and phase velocity)

This particular code very useful to simulate the antenna array design and very effective

Stretches contrast on the image and normalize image from 0 to 1. The main difference of this function to the standard stretching functions is that standard function finds global minimum and maximum on the image, then uses some low and high threshold values to normalize image (values below LowTHR are equated to LowTHR and values above HighTHR are equated to HighTHR)

里面有多种数据拟合函数，可用于matlab数据拟合，简单易学。(It is for Matlab Data Fitting.)

The function femTriangularMeshGenerator() generates triangular mesh for a rectangular shape structure for Finite Element analysis. The outputs are: coords = x and y coordinates of each element nodes cT = nodal connectivity nNodes = Number of nodes The inputs are: Lx = width of the rectangular structure Ly = Height of the rectangular structure Nx = Number of divisions on x- axis NE = Number of elements The example generates 144 elements for a rectangular structure given a dimension 10units by 10units with respect to 8 divisions on x-axis.
