matlab code for PCA or eigenface face recognition.

说明：  无线通信第三章第十一题的答案Jakes Model 锐利衰落信道(Chapter XI of the wireless communications answer to sharp fading Jakes Model)

很好的学习资料，对大家有很好的帮助，学习Matlab 和粒子群算法。(Good learning materials, all of us have a good help, learning Matlab and particle swarm algorithm.)

Most of the string-functions are rather heavily hand-optimized, see especially strsep,strstr,str[c]spn.

说明：  Matlab program to find square root,definite integrals

matlab中LFM信号的源程序。经过仿真验证 (matlab source code in the LFM signal. After simulation)

本代码实现了空域自适应滤波的过程,相当不错的源代码。 (This code implements the spatial adaptive filtering process,)

该函数是实现Costas环仿真的Matlab编程，具有较好的性能(this function is to achieve Costas Loop Simulation Matlab programming, with good performance)

解决最小费用最大流问题，一般有两条途径。一条途径是先用最大流算法算出最大流，然后根据边费用，检查是否有可能在流量平衡的前提下通过调整边流量，使总费用得以减少？只要有这个可能，就进行这样的调整。调整后，得到一个新的最大流。(Minimum cost maximum flow problem to solve, there are generally two ways. One way is to use a maximum flow algorithm to calculate the maximum flow, then the cost side, check whether it is possible under the premise of the flow balance by adjusting the edge flow, so that the total cost can be reduced? As long as this possible, for such adjustments. Adjusted to obtain a new maximum flow.)

这是一个用matlab模拟单缝衍射，光强分布的程序代码(This is a matlab simulation of single slit diffraction, the intensity distribution of the program code)
