coherent-incoherent-image

说明：  模拟退火控制的遗传算法，可求解数值问题的近似最优解(GASA example, which can be used to solve the large scale problem to get a approximate solution.)

二维光子晶体的FDTD法，MATLAB 源程序(Two-dimensional photonic crystals FDTD method, MATLAB source code)

计算MIMO系统中信道容量的程序，包括中断容量和遍历性容量两种(CITIC MIMO system channel capacity calculation procedures, including the outage capacity and ergodic capacity )

RS码的matlab仿真 非常有帮助的东西(RS Matlab simulation code has been very helpful things)

It should be noted that there is still room to improve the speed and the memory usage of the algorithms, using for instance displacement structure algorithms for the RQ decomposition and Lanczos algorithms for the SVD.

bp神经网络通用预测程序，matlab2009编写，可直接输入数据。(bp neural network forecasting process common, matlab2009 preparation, can be directly input data.)

u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A1) r1 = [] for i=1:r for j=1:c if A1(i,j) > B1(i,j) r1(i,j)=A1(i,j) else r1(i,j)=B1(i,j) end end end r1= double(r1(:,:,1)) C=blkproc(r1,[8 8], idct2 ) round(C) C1=idct2(r1) figure imshow(uint8(C)) figure imshow(uint8(C1)) imwrite(uint8(C), dct8x8min.jpg )

说明：  kriging代理模型 进行近似计算的 可以自行改变参数(kriging approximate calculation agent model parameters can change their own-kriging surrogate model to approximate calculation can change the parameters)

GENETIC ALGORITHM OPTIMIZATION

可以实现快速傅里叶的计算，适用于matlab环境(Calculation can achieve fast Fourier for matlab environment)
