在matlab环境中分析FFT原理，认真看看，很快就可以掌握FFT哦(Analysis of the FFT principle in the Matlab environment, take a serious look, can quickly grasp the FFT.)

用MATLAB语言实现的卷积码编码，维特比译码(With the MATLAB language implementation of the convolutional coding, Viterbi decoding)

说明：  用牛顿下山法求解方程：下山因子在计算过程中可以变动，一般选择下山因子时从1开始，逐次将减半进行试算，直到能使下降条件成立为止。若当计算到某步时取不到满足要求的值（或值小到无法容忍），这时称“下山失败”，需要另取初值重新算起。(Descent method with Newton' s equation: down factor in the calculation process can change, usually selected from the 1 start down factor, will be halved for successive spreadsheet until the can down the conditions established. If when calculating the time to take a step not meet the requirements of the value (or values ??too small to tolerate), then the &quot down failed&quot , you need an alternative initial re-counting.)

分析粒子群算法在求解组合优化问题中的运行原理并与遗传算法和 改进的粒子群算法仿真比较． 结果表明 混合优化算法在收敛速度和精度上均有明显的提高(Ｔｈｅ 　 ｍｅｃｈａｎｉｓｍ 　 ｏｆ 　 ｐ ａｒｔｉｃｌｅ 　 ｓｗａｒｍ 　 ｏ ｐ ｔｉｍｉｚａｔｉｏｎ ＰＳＯ ｉｎ 　 ｓｏｌｖｉｎ ｇ 　 ｃｏｍｂｉｎａｔｏｒｉａｌ 　 ｏ ｐ ｔｉｍｉｚａｔｉｏｎ ｐ ｒｏｂｌｅｍｓ 　 ｗａｓ 　 ａｎａｌ ｙ ｚｅｄ．Ｓｉｍｕｌａｔｉｏｎｓ 　 ｃｏｍ ｐ ａｒｉｓｏｎ ｗｉｔｈ 　 ＧＡ 　 ａｎｄ 　 ｉｍ ｐ ｒｏｖｅｄ 　 ＰＳＯ 　 ｓｈｏｗｓ 　 ｔｈａｔ 　 ｔｈｅ 　 ｈ ｙ ｂｒｉｄ 　 ｏ ｐ ｔｉｍｉｚａｔｉｏｎ 　 ａｌ ｇ ｏｒｉｔｈｍ 　 ｈａｓ 　 ｏｂｖｉｏｕｓ 　 ｉｍ ｐ ｒｏｖｅｍｅｎｔｓ 　 ｉｎ ｃｏｎｖｅｒ ｇ ｅｎｃｅ 　 ｓ ｐ ｅｅｄ 　 ａｎｄ 　 ａｃｃｕｒａｃ ｙ)

该例子介绍了zemax在序列模式下融入非序列，光线从每个被定义的场点(Field Point)射向系统孔径，并且穿越非序列性表面(NSC Surface)前的所有序列性表面(In NSC with Port Design, the system uses the system as defined in aperture (System Aperture) and field (Field) in the sequence mode. The light from each field defined in point (Field Point) fired at the system aperture, and through all sequences of non-sequential surface (NSC Surface) before surface)
