cost function calculation for vertical handoff in heterogenous network

求两个序列的互相关函数，或一个序列的自相关函数；并显示了不同功率噪声下的效果。(Sequences for the two cross-correlation function, or a sequence of auto-correlation function and display a different power under the effect of noise.)

针对二维图像和彩色图像的小波分解与重构，使用sym函数(Color image decomposition)

This is a matlab project in which application detect the brain tumour.

好东西，虽然不是很难，但是这样可以节省不少时间，可以把精力投入到难度较大的改进以及应用上了，而不用在大家都会的基本程序上花挺多时间(Good things, though not difficult, but it saves a lot of time can focus into the more difficult to improve as well as the application, and not everyone will be in the basic procedures for the time spent挺多)

该文件为matlab工具箱各种代码，供大家使用。(matlab toolbox code)

可实现微电网中分布式电源的下垂控制，采用三环控制策略，节点既可作为V/f结点，也可作为PQ结点(It can achieve distributed generation droop control in Microgrid, which uses three-loop control strategy. The node can be used as V/f node, the node can also be used as PQ node)

RLS algorithm using IIR

随机游走类似布朗运动，就是随机的向各个方向走吧。 虽然代码没什么技术含量，不过产生的图像实在太漂亮了，所以还是贴上来吧。 产生的图像：(Similar to Brownian motion random walk, is random and go in all directions. Although the code is no technical content, but the resulting image is too beautiful, so it is still Tieshanglai it. graphics layer.)
