cross

this is a matlab code for meshing in finite element method

代码是关于数据挖掘方面的代码。内含4个可以用于多实例学习的分类及作出结果。(Code is on the data mining code. Includes four multi-instance learning can be used to make classification and results.)

说明：  通过matlab产生各种信号，包括四种信号，有正弦，指数，虚指数，复指数信号，内容丰富，是和信号分析同学使用(signal about sin，etc)

说明：  网络函数逼近实例1.首先定义正弦函数，采样率为20Hz，频率为1Hz 2.生成BP网络。用newff函数生成前向型BP网络，设定隐层中神经元数目为10 3.对生成的网络进行仿真并做图显示。 4.训练。对网络进行训练，设定训练误差目标为 1e-5，最大迭代次数为300 5.再次对生成的网络进行仿真并做图显示。(Network function approximation example)

本程序是快速独立成分分析算法的主程序，包含了详细的注释，不含子程序。(This procedure is fast independent component analysis algorithm of the main program, including detailed notes, excluding subroutine.)

roa算子，Ratio of Average,主要用于sar影像的边缘检测-roa operator, Ratio of Average, mainly used in the edge detection of sar images(Roa operator, Ratio of Average, mainly used for edge detection-roa operator sar images, Ratio of Average, mainly used in the edge detection of sar images)

to generate the white noise signal u(n) with uniform distribution

这是一个基于小波变换的二维图相融合算法，是基于医学图像编写的。(This is a wavelet transform based on two-dimensional map of the fusion algorithm is based on the preparation of medical images.)

matlab程序，可以将信息隐藏在每个字节的LSB中(hide message in lsb of every byte)
