this matlab code describes FFT calculation

移动最小二乘图像变形，MATLAB，打开demo2，标定关键点，再标定要变换的位置，(Moving Least Squares image distortion, MATLAB, open demo2, calibration key points, and then calibrated position to transform)

用拉格朗日n次插值方法 对一系列离散点进行插值(N times with Lagrange interpolation method interpolates a series of discrete points)

说明：  粒子群算法优化matlab源代码，效果不错(Particle swarm optimization algorithm optimizes matlab source code, the effect is good)

sift算子中高斯金字塔和DOG的生成，只是该算子的最初步骤(sift operator：the generation of Gaussian pyramid and DOG。it is only the first steps)

非线性调频信号产生程序，根据给定的窗函数综合出相应的NLFM信号(Non-linear FM signal generation process, according to the given window function the corresponding NLFM signal integrated)

合成孔径雷达点目标仿真程序（MATLAB程序）(Synthetic aperture radar point target simulation program)

this is a well data number 3 for RPH sample, stored in las format

用clean方法进行现代谱分析实验，经过运行程序，结果有效，算法简单。(Methods with clean modern spectral analysis of experiments, after running the program, the results are valid, the algorithm simple.)

基于小波变换的图像增强方法，MATLAB实现，个人测试效果不错，供参考。(image enhancement method based wavelet.)
