说明：  matlab 图形图像处理学习，对图形图像学习以及matlab方面应用十分有用(GraphicsandImageProcessing)

this code is used to solve nonlinear equations using Newton, Bisection, secant methods.

Contourlet变换思想，选用拉普拉斯塔式滤波器结构对图像多分辨率分解来捕捉奇异点。(Contourlet transform thinking, the choice of Laplace tower filter structure for multi-resolution images to capture the singularity exploded.)

poisson问题有限元求解通用程序(线性元). 压缩包内exp.m包含了一个实际问题,matlab下直接运行即可,如效率不高,可适当修改网格参数h.(poisson problem of the finite element procedure for solving general (linear million). exp.m compressed package contains a real problem, matlab can be directly run, such as the efficiency is not high, may be appropriate to amend the grid parameter h.)

中值滤波和均值滤波程序，经常用于数字图像处理中，是基本的图像预处理程序(medium filter and average filter program,it is often used in image progress )

九宫格源代码，用matlab编写的程序比较简单，运行时输入B=shudu2（A），A就是需要填写的九宫格。(Squared source code, using matlab procedure is relatively simple, run-time input B = shudu2 (A), A is a need to fill squares.)

采用M2M4信噪比估计算法对QPSK调制解调器的接收端信噪比进行了估计(M2M4 SNR estimation algorithm on the the QPSK modem receiving end signal-to-noise ratio estimated)

说明：  永磁同步电机模型参考自适应matlab仿真(PMSM model reference adaptive matlab simulation)

machine synchrone (essai).

精通SIMULINK系统仿真与控制（是初学者的好教材）(Proficient in SIMULINK and Control System Simulation)
