附件1是关于FFT算法的详细编程，及详细原理讲解，个人认为，这篇论文对从事信号处理，频谱分析很有帮助，特使是进一步理解FFT算法，很有必要阅读。 程序+原理+运行！ 附件2是关于直接运行FFT工具箱进行频谱分析，请大家可以参考对照，对理解FFT算法肯定有帮助！ (matalb fft 频谱分析)

关于MATLAB的教程，十分详尽，适合初学者(MATLAB tutorial on the very detailed, suitable for beginners)

The firefly algorithm (FA) is a metaheuristic algorithm, inspired by the flashing behaviour of fireflies. The primary purpose for a firefly s flash is to act as a signal system to attract other fireflies. Xin-She Yang formulated this firefly algorithm by assuming:[1] All fireflies are unisexual, so that one firefly will be attracted to all other fireflies Attractiveness is proportional to their brightness, and for any two fireflies, the less bright one will be attracted by (and thus move to) the brighter one however, the brightness can decrease as their distance increases If there are no fireflies brighter than a given firefly, it will move randomly. The brightness should be associated with the objective function. Firefly algorithm is a nature-inspired metaheuristic optimization algorithm.
