一个matlab编写的图片放大程序 可供初学者快速了解学习 掌握基本函数(Write a matlab program to enlarge the picture to learn to master for beginners to quickly understand the basic function)

This program matches the curve of the input image to that of the filter image.Based on the selected filter input image will be added with same effect as that of filter image.This is done by finding CDF and curve of filter image then matching this curve of input image to this curve.

说明：  This matlab codes calculates the mutual information and the conditional mutual information based on k-nearest neighbor algorithm.

matlab 数字图像信号的频域分析及仿真 将二维数字图像进行傅立叶频域分析，并且做了图像幅度谱重建和相位谱重建，通过这个例子大家可以明白相位比振幅更重要。(matlab digital image signals in frequency domain analysis and simulation of two-dimensional digital image Fourier frequency domain analysis, and has done a reconstruction of the image amplitude spectrum and phase spectrum reconstruction, by this example we can understand the phase is more important than the amplitude.)

功能: 用基于拉格朗日函数Hesse阵的SQP方法求解约束优化问题:(Function: Hesse matrix based on Lagrangian SQP method for solving constrained optimization problems:)

画电偶极子等势面，电偶极子的三维等势面，可以改变x，y值(Painting equipotential surface dipole)

这是我从一本书上看着例子编的源程序，很好的对学习很有帮助(This is what I look at an example of a book compiled on the source, very good very helpful for learning)

说明：  libsvm的参数c，g的交叉验证子函数(libsvm parameters c, g the cross-validation Functions)

遗传算法程序，包含变异等各个步骤，用于求一个二元函数的极值，条理清晰。(Genetic algorithm, including the various steps of the mutation, for seeking a binary function extremum clarity.)

可以很好地分析信号的包络谱，效果非常的明显，并且已经在matlab上成功运行(Is a good way to analysis the spectral envelope of signal, effect is very obvious, and it has been successfully run in matlab )
