使用蚁群算法并进行改进，利用改进的蚁群算法优化BP神经网络的程序(Ant colony algorithm and improved use of improved ant colony algorithm to optimize BP neural network program)

This a two dimensional level set code where the interface grows with normal speed equal -curvature. The code generates a movie showing the interface motion with and explicit first order in time algorithm with center differencing in space.

傅里叶变换和小波变换重建图像的比较效果，这个程序可以用来实现四个要求：1、FFT和WT重建效果比较；2、通过改变小波来比较重建效果；3、通过改变分解层数来比较重建效果；4、通过改变大系数个数来比较重建效果。其中还有一个计算PSNR的程序(the comparative effect of reconstruction image by Fourier transform and wavelet transform 。 the program can be used to achieve the four requirements: 1, FFT, and WT reconstruction effect 2, by changing the wavelet to compare the reconstruction effect 3, by changing the decomposition layers to compare the reconstruction effect 4, by changing the number of large coefficient of comparative reconstruction results. Including a procedure of calculating PSNR )

短时傅里叶变换逆变换，采用MATLAB编的程序(Short term Fu Liye transform inverse transform)

LDPC编译码仿真。部分迭代编码，不限定H矩阵类型，SPA算法译码。(LDPC codec algorithm in AWGN channel。)

说明：  hyper chaotic transformation

一个简单的小程序，可以随便下载看的，只是做一点简单的说明罢了(A example for GUI)
