用于进行图像类别识别的程序。根据初步的的区域分割结果，对图像之间的区域进行匹配。 (For image category recognition program. According to the initial region segmentation results, the region between the two images match.)

模态分析中位移数据处理的有效程序，可以非常容易的得到位移处理结果(Effective procedures modal analysis displacement data processing can be very easy to get the displacement results)

量子粒子群的matlab程序，有测试函数(qpso matlab)

说明：  “模拟退火”算法是源于对热力学中退火过程的模拟，在某一给定初温下，通过缓慢下降温度参数，使算法能够在多项式时间内给出一个近似最优解。利用模拟退火算法,基于最优下料编码方式,对矩形件进行下料处理。("Simulated annealing" algorithm is derived from the simulation of the annealing process in thermodynamics. At a given initial temperature, the algorithm can give an approximate optimal solution in polynomial time by slowly decreasing the temperature parameter. Based on optimal blanking coding method, simulated annealing algorithm is used to blanking rectangular parts.)

I,Q通道的 噪声过程是高斯的的,而且是互不相关的,他的功率谱也是白的. 因为I和Q通道的噪声过程是高斯的,而且是互不相关的 我们可以得到他们是相互独立(Papoulis,1984). 最后,由于I和Q通道是独立的零均值高斯过程,因此可以推导出:复信号:I+jQ,幅度是瑞丽分布的,幅度的平放是指数分布的,相位角arctan(Q/I)是在(0,2π]上均匀分布(I Q Gaussian noise)

只是一个简单的计算器，做了话哦几天，拿来分享一下。(Just a simple calculator, to do something and oh a few days, brought to share.)

使用的硬件EM1206，POP通信。可以以pop的邮箱通信方式发送邮件(The hardware used the EM1206, POP communication. You can send a message to pop mailbox communication)

The statements below guide us to write the code for the transmission of sensed data to a sink node using cognitive radios in multiple spectrum bands. In doing this we are trying to find the most appropriate modulation scheme using MATLAB simulation.

vectarrow(p0,p1) plots a line vector with arrow pointing from point p0 to point p1. The function can plot both 2D and 3D vector with arrow depending on the dimension of the input
