共轭梯度法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(Conjugate gradient method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)

说明：  这个用matlab写的小程序可以将连续的若干桢图像连接成一段视频(connect a sequence of images into a vedio)

说明：  matlab编写，贝叶斯估计程序，简单易懂。(Matlab prepared, Bayesian estimation procedures, simple and understandable.)

Cooperative spectrum sensing and adapting to the environment, a cognitive radio is able to fill spectrum holes and serve without causing harmful interference to the licensed user. We consider optimization of cooperative spectrum sensing with energy detection to minimize the total error rate.

基于boost电路的光伏MPPT控制，包括matlab光伏模型(Based boost circuit photovoltaic MPPT control, including matlab PV model)

这个程序实现AMLE方法的图像插值。首先，通过入口从输入图像得到一定数量的水平集。起点只是自动选择的。然后，每个水平集的边界被提取出来，图像边界上的数据被记录。最后，通过使用ＡＭＬＥ扩展这些信息重建一个非常接近原图像的新的图像。(This program implement image interpolation by AMLE method. Firstly, get a number of level sets from an input image by thresholdding. The threshold values are chosen automatically. Then the boundaries for each level set are extracted, the image data on the boundaries are recorded. Finally, by using AMLE, extend those imformation to reconstract a new image, which will approximate the original one quitr well.)

matlab的教学课件，包含例子和教程，好用(courseware matlab，nice)

本程序实现QPSK信号，通过瑞利信道后的各部分星座图(The program QPSK signal, Rayleigh channel through each part of the constellation after)

对于声矢量圆阵，比较双重范数约束法和自适应抵消稳健波束形成法得到的波束图。(For acoustic vector circular array, dual comparator norm constraint offset robust and adaptive beamforming method by beam pattern.)
