说明：  迭代法 最简单的方法求取一个阈值 用来分割图像(Iteration threshold method)

这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊，定点，正割，二分法方法。这项工作是我的课程的一部分，在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察，你可以：例如，对于一个特定的公式，一种方法可能运行的迭代次数最少，而另一个将运行更多的迭代，但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)

说明：  关于雷达建模的一本书中很详细的Matlab代码，第2章：雷达横截面(Matlab code about radar system simulation, chapter2: radar cross section)

说明：  本算法是基于高斯分布的梯度边缘检测法，采用MATLAB实现(The algorithm is based on the Gaussian distribution of the gradient edge detection method, the use of MATLAB to achieve)

判决反馈滤波器的工作频率受限于电路速度，本程序通过并行信号处理，可以使其工作于任意高的频率。(The speed of DFE is limited by the timing of circuit. This program speed up the DFE by parallel signal processing.)
