基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

几种beds的计算方法,matlab仿真rev,欢迎分享(Several beds of the calculation method, matlab simulation rev, welcome to share)

说明：  OFDM在AWGN信道下的仿真，用MATLAB实现，一共有6个程序。(OFDM AWGN under the simulation, using MATLAB, a total of six procedures.)

music算法界面实现，使用matlab中的gui产生了良好的互动界面(Interface to realize music algorithm, using matlab GUI produced in good interactive interface)

用MATLAB把两幅图片拼接起来，首先需要在matlab输入两张图片，然后用相应的代码即可完成拼接。(The two images together using MATLAB together, first in matlab enter two images, and then use the appropriate code to complete the mosaic.)

能够在一定TDOA估计误差下给出定位精度误差 /3d(this program can esitimate the location accuracy in 3D enviorenment when defing the tdoa error)

说明：  lda是一个集合概率模型，主要用于处理离散的数据集合，目前主要用在数据挖掘（dm）中的text mining和自然语言处理中，主要是用来降低维度的(lda is a set of probability models, mainly for dealing with discrete data sets, the key used in data mining (dm) in the text mining and natural language processing, is mainly used to reduce dimension)

this is new approach for fuel cell control.it is really helpfull.

读取双指数脉冲波形 并分析其能量的频率分布(The frequency distribution of double exponential pulse waveform to read and analyze its energy)

求变截面梁的模态，目前只支持一处变截面，可以自己修改尺寸数据，简单好用(mode shape of the stepped cantilever beam)
