给出了分数阶傅里叶变换的具体实现程序，阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)

基于时域有限差分法的电磁波二维传导方程，MATLAB编写，可作为二维正演模拟，也可作为MATLAB的教学演示。(FDTD method based on the electromagnetic two-dimensional conduction equation, MATLAB prepared, can be used as two-dimensional forward modeling, but also as a teaching demonstration of MATLAB.)

用斐波那契额法求函数极小值，它是一种双向收缩的方法，它的收缩率是0.618(Fibonacci amount of law and the function minimum, it is a two-way contract, the contraction rate is 0.618)

说明：  一个三d加密图像程序，有点复杂，可以参考注释理解，希望有用。(A three-d the encrypted image program, is a little more complicated, you can refer to the Notes to understand, I hope useful.)
