Newton rhapson to solve a polynomial fuction

雷达系统中用于计算起伏目标的检测概率，适用于Swerling I型目标。(Used to calculate the undulation target detection probability, applies Swerling I target.)

说明：  to check if two arrays have common element

CIC滤波器的原理以及FPGA的实现，CIC滤波器的仿真(CIC filter FPGA implementation of the principle and, CIC filter simulation)

MATLAB实现的高光谱图像的端元提取，可以自己下载高光谱图像，然后修改下程序就能用了。(MATLAB implementation of hyperspectral image endmember extraction of hyperspectral images can download and modify the following program can be used.)

用MATLAB编写的图像灰度处理程序，有不足之处，还望大家批评指正。(Prepared using MATLAB image processing, there are deficiencies, we hope that criticism.)

This is an matlab source code for smoothed particle hydrodynamic simulaiton. It include matlab routines and input data.

Script originally intended for use in oceanography/fluid dynamics. Use: >> ipdv(X,Y) (0,0) default initial position or >> ipdv(X,Y,Xo,Yo) (Xo,Yo) initial position 2D vector components (X,Y) are used to plot the vectors one after another, i.e., next vector starting at the end of the previous one (via Matlab s quiver.m ). This function handles NANs (Not-A-Number) by putting Zeros in their place, thus allowing the Matlab cumsum.m function to compute the progressive positions (Matlab function cumsum.m doesn t skip Nans). NaNs produce discontinuities in the graphic.

关于光流法的一个外文论文，很好的讲述了光流法算法(An optical flow method on foreign language papers, very good about the optical flow algorithm)
